On signing day eve, several Bulls prospects still up for grabs
A few final USF-related recruiting morsels on the eve of national signing day, when all the conjecture dies and commitments become binding:
 Jesuit OLB Vincent Jackson confirmed to the Tampa Bay Times he will announce his college of choice at some point Wednesday morning.
Deemed a three-star prospect by 247Sports and Rivals.com, Jackson is part of the USA Football under-19 national team that faces Team Canada in Friday night's International Bowl at the University of Texas-Arlington.
His two finalists are believed to be USF and Virginia, the last two schools he visited.
 Despite prior reports of a commitment to Marshall, Sickles OLB/DE Josh Black still has USF on his list, Gryphons coach Brian Turner said Tuesday morning. A teammate of Bulls commitment Zach Hudson, Black visited USF three weekends ago, and Marshall the following weekend.
 The Bulls reportedly are on the short list (with UCF and Texas) for Lakeland Victory Christian DT Chris Nelson (6-foot-2, 295 pounds).
 Ocala Vanguard QB Adam Robles has generated interest from USF but hasn't received a formal offer, Vanguard coach Alex Castaneda said Tuesday. Robles ultimately could join the Bulls as a preferred walk-on, or even snag a late scholarship if one becomes vacant.
Robles (6-3, 185) has thrown for more than 4,000 yards over the past two seasons. Teammate Kano Dillon, a tight end, is expected to sign with USF on Wednesday.
"He's going to wait and see what happens because everything's crazy on signing day," Castaneda said. "He's an extremely good player."
 Various reports and online projections indicate Immokalee three-star RB D'Ernest Johnson (5-10, 180) will sign with USF.
