Geno's take was that Izzo's players love him, would go through wall for him, and aren't complaining.
- "Players still love you & come back for more" - OK
- "Players feel abused" - NOT OK
Geno yells, cusses, taunts and publicly criticizes. He has a reputation for "knowing what buttons to push" for each individual player, and he also seems to know the limits for being tough on each player as an individual.
He employs 3 ethnically and age diverse females on his coaching staff who represent 3 different generations (big sister, mother, grandmother?), and each of whom was a high-level/elite WCBB player in her day. These ladies are close to the players (often playing the "good cop"), and I'm sure they give him plenty of feedback if they think he's getting close to the line.
Geno definitely passes the "players still love you" test.
