I don't agree. That 06 team had both high end talent and depth that not many cup winning teams have had upfront.
that line of Staal, Stillman, Cole (and then Recchi) was just as dominant and if you paid too much attention to them, the RBA/Williams line (with Ladd at the end of the season) would make you pay. And after the deadline, if you managed to stop those two lines, you had Whitney-Weight-Cullin that could burn you.
Staal: 45G, 100P
Williams: 31G, 76P
Stillman: 21G, 76P
RBA: 31G, 70P
Cole: 30G, 59P (in 60 games)
Whitney: 17G, 55P (53 games)
Cullen: 25G, 49P
Recchi: 28G, 64 points on the season
Weight: 15G, 57 points on the season
Then for depth:
Ladd, Vasicek, Larose, K. Adams, C. Adams.
