Besides our "bigger name" guys like Morrissey, Petan, and Comrie, I have been very interested in the last few years with Lowry and the last year with Lipon.
Obviously we need Morrissey to turn out, Petan has been putting up a tonne of points and we're waiting to see how he will do at the next level, and Comrie (along with Helle and Hutch) represent potentially our goalies of the future, but I think if guys like Lowry and Lipon (and Kosmo), can also make the jump to the NHL (in a most likely middle 6 role for guys like Kosmo and possibly Lowry, and bottom 6 for possibly Lowry and Lipon), those might be the type of graduations that start to put the Jets into the next level.
Not saying that they are more important than Morrissey becoming at worst a 2nd pair guy, or Comrie becoming a legit goalie, because those things have to happen too. But I think it's the teams that get significant contributions from young (and cheap) guys, and sometimes unheralded guys that go far. Plus, I would think we might need the types of games that hopefully these guys can bring one day to compete with the Kings of the league.
I hope that both Lowry and Lipon can improve again next season, and both get some game action with the Jets here and there.
