I like Callahan overall BUT he is not able to adjust from his gameplan when it is clearly not working.  He should have abondoned the run up the middle because it was not working.  Swing Lucky out for receptions (which worked) and throwing downfield which also worked.  NU did this in the first and last 10 mins of the game and that worked.  Tom Osborne (love him) use to do the same thing though.  Frank's teams had no other choice.  The West Coast offense is suppose to be able to 90% run, or 50/50 run/pass or 90% pass on a team.  Callahan stuck with 50/50 when he should have gone 90% pass but without those swing passes.  The passes under 5 yards we not working.  The downfield passes were.

Why did Wake Forest keep doing those WR end arounds?  Because they worked.  You have to stick with what works.

Defense up the middle and tackling is a different story.
