Deshawn Purdie's memory of miscues is short.
The case study started with a third-quarter fumble. Ball security has been a focus for Charlotte's true freshman in his transition from Milford Mill Academy, and South Florida's Mac Harris caught him at the right time on a linebacker blitz.
His spot on the sidelines was temporarily vacant before he was right back, ready to go out with his offensive line. Defensive pressure on the following drive came before an interception, returned for a touchdown, and made it consecutive drives with a Charlotte turnover.
South Florida's 59-24 win over the 49ers on Saturday was boosted by the 17 points it created off a third straight turnover when Purdie's fumble against another Bulls' blitz was returned for a touchdown as well.
