These are interesting opinions. However, the only thing you can truly measure is the score. The best indication of a player's effectiveness in a team game is the team's performance when each player is in the game.
You can say Collins is "tough as nails" while I might say "Collins is soft as a marshmallow." Those are opinions.
However, the numbers say clearly that Collins mis-used his players last year. I don't have data for prior years, so I don't know if last year was representative or just a fluke.
Our "starting lineup" (Nance, Beran, Kopp, Buie, Audige) was worse than our average lineup last year, Definitively. The starters scored 83.2% of the points they allowed. Collectively, our other lineups scored 90.3% of the points they allowed. That can only be described as "misuse."
A second example of misuse of the roster was playing Young and Gaines together without either Nance or Beran, a whole assortment of lineups I called "Young and 4 guards." That collection of lineups played a full 16% of the minutes and got destroyed 244-161 in 20 Big Ten games. My conclusion is that Coach Collins gave away 5-7 points PER GAME based on the lineups he was sending out there last year.
