I believe that the ability/opportunity to develop talent at the NHL level is not over, but with the play of last season's team, the time is nearing in which it will be more of an exception. The early couple of years of the Sabres rebuild provided the perfect circumstance to avoid bad contracts with NHL plugs in favor of development at the NHL level - as we could bring up young talent without the pressure of having to perform at a level higher than they were capable of when they started their NHL tenure. For the most part, it has worked out well for guys like Quinn, JJ, Samuelsson, Krebs, Cozens and yes - even Owen Power. That same set of circumstances also provided the opportunity for guys like Dahlin, Skinner, Tage, and Mitts the same room for growth as they redefined their games in the wake of the Krueger years.
For Kulich, I think the best thing for him and the Sabres organization is for him to play most of the year in Rochester and learn how to combine his offensive prowess with defensive play so that he becomes a complete 200 foot player. Let him be one of the top forward callups which will give him the opportunity to see how what he's been working at the AHL level translates to the NHL. I'd also keep him under 10 games, if possible, to allow his contract to slide. Same for Rosen as well, though I think his contract will slide this year because of his age.
I do think that Rousek has earned a serious look at the NHL level and also believe that Victor will be around until the trade deadline. Whether in Buffalo or to the team he would be on had he been traded, this is a contract year - so you'd expect that the team he's on will be getting the best of Victor as he looks to secure his next contract. That will mean scoring for sure, but will also mean improved all around play. I'm hoping the Sabres will be the beneficiary of the all around Victor until Jack Quinn returns - after which time the Sabres should look to move him - likely at the deadline and hopefully at a high point relative to performance.
