On the first point, I think talking about 'tackle football' in the playoffs is letting everybody off the hook here. Do people remember what the NHL looked like in 1995? Now THAT was tackle football on ice. Players could literally water-ski while hanging onto players who were trying to maneuver inside the offensive zone. It was awful. And it very clearly hindered skill players.
Nowadays? Nah. People want to believe that shutting down the Penguins in the playoffs has been a very difficult task, something that has been aided by officiating and external factors. But the simple truth is it really hasn't been that hard to shut the Penguins down in the playoffs. Staunch defensive systems, shutdown D-men, shutdown centers, a hot goaltender. Sure, the officiating isn't where THIS team would want it, but it's where it usually is come playoff time. Adjustments aren't being made (shockingly, right) by this team in the playoffs. Excuses are for losers, this team has deserved their playoff fate since '09.
On the second point, I disagree with the notion that Morrow and Iginla "didn't want" the role of leader here. It's pretty hard to be a leader when you are in and out of the lineup, up and down the lineup (as Morrow was), or when you don't seem to have a role on the team (as Iginla did). Iggy was 'the man' in Calgary, he came here and his coach basically drew him the short straw, what was he supposed to do?
Iggy EASILY could have been a Guerin-like leader for this team...but he never got Guerin's role (Crosby's RW).
