I would mostly agree with your analysis of the transition game. Goes along with my "when they play well, they play REALLY well, when they stink, they REALLY stink" quip; sometimes the D makes some great choices, a lot of times they just don't.
However, not sure the lack of depth is entirely correct, in my maybe not so useful opinion. I've seen the freshmen put plenty of shots on net, but in the stats we see, only the ones that go in the net really count, for both the actual goal scorer and the helpers. Again, it may not be the talent that is missing. It may be some X-factor that we as armchair coaches can't see. I did hear Appert say before the Yale game that we have three recruits coming in that are already NHL drafted. I know that doesn't mean everything, but it is nice to see the guy can still recruit.
As for our inconsistency, I thought that might be obvious. Look at our W/L/T record over the whole season. You'll see few streaks, if any.
