Won't all the other teams that had freshmen be better too?
To answer your question:
if you are saying the team will be better - that depends on who they loss as seniors
if you are saying will the freshman get better - then YES
However, Do all teams in the Big Ten have as many freshman in key spots as NU.
Freshman or not, the point is other teams will get "better" as well. So, you have to ask yourself this... Do you think our freshman will improve that much that they can overcome other teams players growth? Also, is our coaches good enough to develop our players enough to matter?
I say, no, Tim is not good enough to do just that. The freshman have gotten better this year, true, but it has been fairly normal improvement. What I mean is the improvement is normal for freshman that are playing as much as they are.
