I think your numbers re wrong.
Virtanen is listed as 6'1
https://www.nhl.com/player/jake-virtanen-8477937
Jagr ovechkin and bertuzzi are all 6'3
https://www.nhl.com/player/todd-bertuzzi-8459444
https://www.nhl.com/player/jaromir-jagr-8448208
https://www.nhl.com/player/alex-ovechkin-8471214
Lindros is 6'4
https://www.nhl.com/player/eric-lindros-8458515
It seems to me that bertuzzi and jagr around 230 while lindros and ovechkin are around 240.
Virtanen is around 210. That 2-3 inches difference is equating closer to 20-30 pounds of weight difference. I'd say it sounds like a rather reasonable difference.
Eliteprospects lists Ovechkin at 6'2'' (187 cm) and Jagr at 6'2'' (189 cm).

I'm curious as to the actual measurements.
Bertuzzi was definitely 245 lbs in his prime.

The language took a beating after Al MacInnis got hammered into the immovable object (the old-style seamless glass in Vancouver) by the irresistible force (Todd Bertuzzi of the Canucks. Bertuzzi's weight is usually estimated at 245 pounds but is said lately to have topped out at 260-plus ... whoomph!).

...
Bertuzzi can fend off a frustrated foe with a beefy forearm, power to the net with one hand on his stick and either dish off a fabulous feed or whip the puck home. That dominance was never more evident than during a league-leading 15-game point streak to start the second half of last season. Then, in March, the 6-foot-3, 245- pound nightmare on skates had 12 points during a crucial six-game road trip -- including a memorable hat-trick performance in Pavel Bure's debut with the Rangers.

Jaromir Jagr played at 240 lbs in his Ranger days, although indeed, this source seems to identify him as being 6'3''. In the late 1990s, he weighed 225 lbs.
New York's Jagr feels as unstoppable as ever; Sabres have hands full; 'You can't really shut him down completely': [National Edition]
Traikos, Michael. National Post [Don Mills, Ont] 01 May 2007: S5.
TARRYTOWN, N.Y. - Jaromir Jagr loves playing at Madison Square Garden for the same reason he once dressed in drag at a charity event in Czech Republic: He craves the attention.
Even when he is not wearing woman's clothing, the 6-foot-3, 240- pound player is hard to ignore.
...
This is a guy who, at one point, weighed 208 lbs.
Jaromir = Mario Jr.; Jagr's number etched in Czech history: [Final Edition]
JOE LAPOINTE New York Times. Edmonton Journal [Edmonton, Alta] 16 May 1992: H2.
...
Lemieux is taller than most hockey players at six-feet-four. Jagr is six-feet-two. Lemieux is heavy for a hockey player at 210 pounds. Jagr is 208. A sign in the Civic Arena on Wednesday night pointed out another eerie similarity. It scrambled the letters of Jagr's first name to say "JAROMIR = MARIO JR."
...
Mario Lemieux, also mentioned in that article, ended up weighing about 240 lbs in the latter part of his career.
Excerpts on Mario Lemieux's comeback game:: [Final Edition]

Some wonder what will happen to the newly publicity-conscious Mario once the tiring tedium of hockey routine settles over him again. They wonder how long his weights-and-bikes workout regimen, which has him at a well-muscled six-foot-four, 238 pounds, six pounds heavier than when he retired, will last when he starts getting banged up.
...
Lindros played at 235 lbs; he found that he was too heavy at 250 lbs.
Is Eric Lindros finished as an elite player?:: [Final Edition]
Matheson, Jim. Edmonton Journal [Edmonton, Alta] 17 Sep 2003: D2.
...
Lindros, who has suffered seven concussions during his career, at least managed to stay in one piece last season. His head was in the game for 81 nights, but his hands and legs let him down. He was 250 pounds; too much weight and too much baggage after his run of injuries.
"I thought he was too heavy. He's 236 pounds now, seven percent body fat. He was one of the top guys in every conditioning category we had at camp," said Rangers GM Glen Sather, who badly needs Lindros to return to some semblance of his old wrecking-ball self if the Rangers hope to be playoff contenders.

They learned he stands precisely 6-foot-4 and weighs exactly 235 pounds.

This is how the entire Legion of Doom measured in 1997:
Sabres turn attention to stopping Flyers' Legion of Doom
Gleason, Bucky. The Globe and Mail [Toronto, Ont] 03 May 1997: A.21.
...
Lindros (6-foot-4, 240 pounds), John LeClair (6-3, 230) and Mikael Renberg (6-2, 220) combined for 235 points during the regular season even though Lindros missed 30 games. They had 19 points in the Pittsburgh series.
The Sabres won the season series 2-1-1 and effectively shut down the Flyers by matching up the Lindros line with speedy forwards Michael Peca, Jason Dawe and Dixon Ward. Ward (6-foot, 200) is the biggest among the three.
"We're not going to intimidate them with our size, but maybe we can intimidate them with our speed," Dawe said. "We're not going to turn away from the hit if it's there, but we don't expect to be knocking Eric Lindros or John LeClair too far."

Bold and beautiful: Canucks winger is 'stinking strong,' with offensive talent to boot: [Final Edition]
Matheson, Jim. The Vancouver Sun [Vancouver, B.C] 28 Dec 2002: C12 / Front.
...
How good is he? For starters, he's taken over from John LeClair as the best big package in the NHL. Power forward is the most overworked term in the league. Anybody who can score and muscle is supposed to be in that category -- which means Bill Guerin and Keith Tkachuk, Brendan Shanahan, LeClair and Iginla (before he got all his injuries this year).
But Bertuzzi is the ultimate power guy. He's 245 pounds; nobody else has ever been as big and as light on his feet. LeClair is 226 pounds; Tkachuk 225, Shanahan 218, Guerin 210, Iginla 205. You can throw Jaromir Jagr in there, too, but he's 60-per-cent finesse and 40-per-cent power at 234 pounds.
...
Alex Ovechkin plays at 239 lbs.
Could Ovie break unbreakable mark?; Prolific scorer
Kuzma, Ben. The Province [Vancouver, B.C] 14 Jan 2016: A.70.
...
Ovechkin has elite skill and thinks the game at another level, so it's easy to imagine him putting up 40-goal seasons, even with a league average of 2.7 goals per game per team. At 6-foot-3 and 239 pounds, the 2004 first-round draft pick willingly exudes a hard driving, bulllike mentality, and that will take a toll over the years. He may have to adjust, and that could hurt the goal total.
...
In 1993, Keith Tkachuk weighed 210 lbs; in 2003, he weighed 225 lbs.

Now they're one of the most feared attack units in the NHL. The rugged Tkachuk provides a physical presence -- he's 6-2, 210 pounds -- that gives linemates room to manoeuvre.

Who's the hardest hitter?:: [Final Edition]
Bell, Terry. The Province [Vancouver, B.C] 24 Feb 2003: A46.
...
Feisty forward Keith Tkachuk of the Blues, 6-foot-2 and 225 pounds, can often be found going after somebody for a hit or a fight.
...
Of course, after blowing up to 260 lbs and then being suspended, Tkachuk settled on a weight of 235 lbs for the remainder of his career.
Cam Neely, who is 6'1'', weighed about 218 lbs in 1993-94.
Neely can't believe roll he's on: [SA2 Edition]
Frank Orr TORONTO STAR. Toronto Star [Toronto, Ont] 05 Mar 1994: E3.
....
Neely, who became a Bruin in an '86 trade with Vancouver Canucks, became the NHL's prototype power forward when he scored 55 and 51 goals in '89-90 and '90-91, plus 28 goals in 40 playoff games.
In style, he's much like the great Gordie Howe - big (6- foot-1, 218 pounds), an effortless skater, very strong and tough, and owner of a little man's soft hands. Like Howe, there's a strong economy in Neely's play. No stride is wasted in a game of straight lines, going directly to the puck or where it's likely to be.
...
Virtanen's game depends on strength, so I can't see him thriving at 208 lbs. I think 220 lbs, maybe 225 lbs should be his prime weight. All of these other players gained significant weight by the time they were in their mid-20s.
