I think Frank's done a good job at improving offensive spacing (of the entire team).
That's a quasi-skill imo.
Any real skills (like go-to moves, improved shooting, dramatically improved ball handling) would be difficult to develop during a D1 college season. Frank may have improved Mike on some of these skills in the off season, but we would have likely seen the results beginning with Sac. St. JMO
Quality post.
It's the coaches job to capitalize on our players skills and find mismatches (particularly enjoyed when walker had the white guy on him in the post and beaz making the entry pass) Also, coaches need to give certain players a little bit of freedom to create, imho.
There's not enough time for coaches to focus on players individual skills during the season, Frank is more concerned with putting in new sets on offense and defense, scouting, radio show etc.
