Jeff Capel was a head coach long before he came to PITT. So he had experience and winning records at other stops. He didn't "learn" how to be a head coach at PITT.
"VCU, Capel guided the
Rams to a record number of wins (79) and the highest winning percentage (.658) of any Division I program in the Commonwealth of Virginia. Following the 2003–04 season, Capel was named both the Richmond Times-Dispatch and VaSID state Coach of the Year after leading the Rams to their first NCAA Tournament appearance since 1996."
Overall record at VCU was 83-69 with 2 tournament appearances
"Entering his fourth year, Capel's record at OU was 69–33 (0.676) overall, 28–20 (0.583) conference, with 2 NCAA Tournament Appearances, and one Elite Eight appearance. In the Big 12, Capel had yet to win a Conference tournament Title or Regular Season Title. Capel was averaging 21 wins per season (21–12) and 8 conference wins per season (8–8), almost on track with his predecessors Tubbs & Sampson."
Overall record at OK was 83-69 with 2 tournament appearances
This buys you some time but for RED he doesn't have the history of being a successful head coach at other stops.
