It's been a great 24 hours for Bulls head coach Willie Taggart.
Taggart got to see his best friend Jim Harbaugh take his 49'ers to the Super Bowl - and then the day got even better.
Runningthebulls.com has confirmed that four-star defensive tackle Derrick Calloway has decommitted from Louisville and has changed to USF.
Multiple sources close to both Louisville and South Florida have verified that Calloway has changed his mind.
The 6-foot-1, 310 pound is rated by Rivals.com as a four-star and is the No. 18 defensive tackle in the country.
Calloway finished a visit to Louisville and decided that USF was the better fit.
Calloway is the fourth player to verbally commit to USF this weekend, following Mike Love from Countryside (Clearwater, Fla.), Hassan Childs from Osceola (Kissimmee, Fla.) and Eric Mayes from Booker (Sarasota, Fla.).
All four players line up on the defensive side of the ball.
