I vehemently disagree. You need a balanced team and you don't achieve that by simply adding the biggest names regardless of fit. It's not a NHL 2020.
Who does Hall replace on the powerplay? Or are you paying Hall 11M to play second fiddle? It's real easy to say Tkachuk and Gaudreau can move over to right wing but what if they don't work? And moreover, the team could have already shifted them over to play Bennett or Mangiapane there or move Lindholm to centre but they're not.
And frankly, Hall simply isn't worth the 11M+ he's likely going to get in free agency. He's an injury prone reckless player that won't age well.
The Flames have two actual needs in a top-nine centre and two or three right wingers (all preferably shooting right). And Treliving's recent history suggests he's aware of this with his attempted Kadri and Stone deals.
Apparently Vegas is just playing NHL 2020. Because all they do is add the best players they can, around every turn, every year so far. They're only the favourite to win our division by just about everyone, and one HELL of a team.
If a guy like Tkachuk or Gaudreau can't play RW; it'd be shocking. Both guys have done it in the past, and Matthew's even said something along the lines of 'we're professionals in the NHL, we can take a pass on the backhand."
The reason Calgary hasn't moved Lindy down yet is the fact no one can pick up that slack he leaves on the top line. Bennett and Mangi have been near replacement level. You can't replace a damn solid player with two far inferior players.
On PP1? Just move Lindy to PP2. He's a great right handed shot, but Hall is an elite player; he can pick up that handedness slack easily. Plus that second unit then actually has a finisher on it with Lindy; which improves it as well (because it's been garbage for a long time).
Our needs are to get better. To get better players. I don't care about handedness. If you can add a league MVP and lose a few pieces that are replacement level; you do it 10/10 times.
