TAMPA — Senior receiver A.J. Legree, who appeared poised to finally emerge from USF's logjam at receiver, is expected to miss the season after tearing his ACL during a recent practice, coach Willie Taggart confirmed."Just kind of a freak incident, no contact or anything," Taggart said during the Bulls' media day Wednesday at the Sun Dome. "Just running a route and his foot got stuck in the ground and he tore it. Hate it. He was having a heck of a spring. Had a really, really good summer."A Kentucky transfer who sat out the 2014 season, Legree — a state champion high jumper at Fort White High — had three catches in seven games last season. Taggart said the school will seek a medical redshirt for the Gainesville native. USF ODDS AND ENDS: Taggart had an interesting take when asked about the preseason progress of 6-foot-5 receiver Marquez Valdes-Scantling. "Early in camp, (cornerback) Deatrick Nichols was all over him. All over him," Taggart said. "And here lately, he's come alive and is showing us all what he's capable of doing." … First-year receivers coach T.J. Weist said Plant High alumnus Jordan Reed "has probably improved the most of the slot receivers." … Coaches continue heaping praise on redshirt freshman defensive end Kirk Livingstone, projected to start opposite the "Bull" defensive end. … Woodie said Danny Thomas is backing up middle linebacker Auggie Sanchez, with Texas transfer Cecil Cherry still trying to grasp some concepts.
