Yes, recruiting is only half the battle.
I didn't watch the Gophers much during Monson's tenure (I was still new to the state) but looking back at the consensus recruiting rankings, I see the following (with consensus recruit ranking noted):
Rick Rickert (#9)
Kris Humphries (#10)
Adam Boone (#33)
Aliou Kane (#75)
Vincent Grier (#83)
Lawrence McKenzie (#85)
Sports Reference lists only Top 100 players so I don't know how many of Monson's recruits fell within the next fifty or so below that.
Pitino has recruited only the following Top 100 players:
Coffey (#40)
Washington (#61)
Oturu (#50)
Obviously, the bottom line for a program's success is how well players perform, not their rankings based on their prep years. Players like Murphy, Lynch, and Carr were underrated but I would guess some of Monson's were as well.
Neither coach recruited terribly (although Pitino had some very costly clunkers) but neither coach got the job done.
