You wonder about Miles' offensive coaching acumen. Yes, we know about the personnel issues. But that doesn't explain the team's disorganization and general lack of purpose on far too many possessions.
You wonder about player development. Nebraska, in finishing 13-18, had at least two veterans take startling steps backward in overall performance.
You perhaps even wonder a bit about Miles' recruiting prowess, considering some disappointing early returns from young players. Nathan Hawkins and Deverell Biggs already are out of the program. Walter Pitchford and Terran Petteway obviously have been key contributors. But Miles needs much more from Nick Fuller and Tai Webster, as well as true freshman center Jake Hammond.
If some young players don't improve rapidly, the pressure intensifies for Miles' touted 2015 class to live up to hyperbole. The best news about Glynn Watson, Jack McVeigh, Michael Jacobson and Ed Morrow is they all appear to have potential as scorers. This just in: Nebraska needs some punch on offense.
Miles will count on Andrew White, the Kansas transfer, for immediate help with outside shooting. But I think Nebraska is overly reliant on three-point shooting. Miles identified his team's deficiency in that area as the No. 1 problem on offense this season. That made me cringe. Three-point shooting generally comes and goes.
