Ask Richard Pitino if he altered his coaching to achieve defensive improvement this season, and he'll joke that he went to a special class this summer. (He didn't.)
Then he'll suggest that becoming a better defensive coach required acquiring better defensive players. (He did.)
The most obvious difference between last year's enablers and this year's naysayers is center Reggie Lynch, who set the Gophers men's basketball single-season blocks record. His strength and ability to time his leaps have altered opponents' plans as well as their shots.
There is a more subtle reason for the team's defensive improvement, and his name is Amir Coffey.
Pitino was obligated to recruit Coffey. He was a great Minnesota high school player at Hopkins whose father played for the Gophers.
Instead of landing the next Kris Humphries, who any day now will be recording his first basketball assist, Pitino wound up with a versatile, selfless player who adapted surprisingly well to playing major-college defense.
With Lynch intimidating shooters near the basket and Coffey hurling his long frame and arms at shooters on the perimeter, the Gophers' defense has improved immeasurably.
And measurably.
