My apologies, I meant to say his play will end up taking a dip as the years pass by. But I have to disagree, I think his 10-11 season was his best one. He was playing really well until the Chara slapshot.
The only reason Callahan plays in all those situations is because this roster is very flawed. By the virtue of your descriptions, I can easily say Mike Richards, TJ Oshie or Logan Couture also fit that description. All three can play in any situation in the game. Richards averages 16:30 minutes per game, Oshie is 19:05 and Couture is 18:15. All three play far less than Ryan Callahan's 21:26 and are superior players.
All three of those players are depth players for their respective, contending teams. Callahan is the team's leading ice time getter amongst forwards. Callahan should be a depth player on a contending team. If the Rangers continue to get fooled into building around him, enjoy perennial 8th seed 1rst round exits.
I think all of your comparisons are quite spot on, although I'd contend that while you classify them as depth players, I think all of them are looked to and counted on as primary scoring threats.
I think we'll agree that the difference is the coaching. The blues, Sharks, and Kings, to my knowledge, tend to have more traditional, set 1st, 2nd, 3rd lines. Torts seems to prefer 3 balanced scoring lines, and Callahan is always going to be on the one that gets more ice time, and he should be. He scores at a 30 goal or higher pace, and he's been doing it consistently (please, don't bring up Clarkson. His year was an an abberation, and everyone knows it).
The only other scorer we have who has a history of putting pucks in the net at that pace is Nash, and currently, while Stepan has been ripping **** apart, he's shooting at a 15.5% average, good for 68th in the league. But, this includes players who have 2 goals on 20 shots, so among shooters with over 100 shots, he has the 10th highest percetnage in the entire league He's only behind Kunitz, Carter, Stamkos, Tlusty, Vorachek, Brower, Taveres, PAP, and Kane. It's incredible, but can we continue to count on this?
a 30 goal scorer on any team is more than support. We tried building the team off of high end talent, and it didn't work, so it looks like we're going back to the "meh up top, solid through the middle" philosophy of forward corps building.
