From 72-73 when Robinson joins the team through the end of the dynasty in 78-79, the Big Three are 1,2,3 in +/-
Savard +402 (4 Top 5 Norris finishes 4, 5, 5, 5; one 2nd Team All-Star, two "3rd Team AS")
Robinson +385 (3 Top 5 Norris finishes 1, 2, 3; two 1st Team All-Stars, one 2nd Team All-Star)
Lapointe +317 (6 Top 5 Norris finishes 2, 3, 4, 4, 5, 5; one 1st Team, three 2nd Team All-Stars, one "3rd Team AS")
Orr if healthy is assuredly the leader in EVERYTHING and Park and Potvin are individually superior players, but AS A UNIT the Big Three's dominance is simply unparalleled. 5 Stanley Cups in 7 seasons and they lead the league in fewest goals allowed in each of those seasons. And I feel today we tend to look at the pairing of Robinson-Savard and overlook Lapointe. Pointu is 3rd in defenseman scoring behind Potvin and Park during that time and is 2nd in goals.
In playoff scoring during that period:
Park 72 pts.
Robinson 64 pts.
Potvin 58 pts.
Lapointe 58 pts.
Savard 56 pts.
Along w/ Dryden they were the backbone of the best defensive team post-expansion and maybe ever.
