Injuries or not to the upperclassmen, with the exception of Hill and Miller, the freshman line remained intact from the first game, and usually skated as the second line in the latter part of the season (only one game missed by Blackburn), and played more minutes than all but the first line, I think. Wyse only missed three games at D, which is fortunate, given the injuries on the blue line. Maybe Fregona deserved more ice time.
The point is, you cant use last season as an argument for Umile changing his philosophy when not one JR or SR missed a single game (outside of injury) or was bumped out of their role by a FR. The reality is that there were just fewer upperclassmen and position battles last season (especially at the forward position).
You mentioned Fregona in your post - I'd argue his usage indicates more of the same from Umile. Despite his requiring the largest adjustment among FR, he was immediately far more talented (and simply a better player) than at least Miller, Cefalu or Hill. Yet he found himself often in the stands in deference to the older options...
This season, we will be able to determine I Umile is going to capitalize on his last chance to change his stripes (assuming he's making the decisions).
There is a FR goalie with - at least - tremendous potential to challenge a pair of completely underwhelming fourth-year players. Robinson should at least get a chance to win the job. A REAL CHANCE.
There are 3-4 capable defenseman with high ceilings incoming, but 5-6 returning letter winners, including Wyse and 3 upperclass regulars. How many FR will play? On talent alone I think it should be at least three. I doubt that's the case...
Up front they bring in at least two forwards who should skate consistently. Kelleher, while not his brother, is likely to immediately be far more skilled than many of the top offensive options returning. It wouldn't surprise me if he is consistently playing on a lower line in lieu of lesser players. Even his brother had to toil...
MacAdams should immediately skate ahead of most of the role players returning. Will he? Perhaps Umile sits Cefalu more often, but I doubt he even considers touching Miller's ice time despite the fact that MacAdams is simply much better at playing the role Miller is asked to fill. His easiest path to playing time is probably Unile sitting down an underclass skill guy for 'defensive' purposes. Tough break Fregona, you're the better player here too...
I'll be surprised if Miller, Chanter, Dawson, Boyd (?), Tirone and even Cefalu (among others) aren't playing regularly next year - ahead of better, younger players - because under Umile that has always been the case. Why would he change in his final season?
