South Carolina ('05): 1st half
Auburn ('08, probably more JC's fault): 1st half
UCLA ('08): 3rd quarter, with a TD lead.
It's not that these were in key, late-game situations. It's that we lost the games. What do you expect? They were during the 2005 and 2008 seasons. By my memory, Foster only ever lost one fumble in the 4th quarter. And that one (Penn State) is burned into our memories. But he takes too much heat for the others. Not his fault the team was too awful to claw back (in the case of Auburn) or maintain the lead (Carolina, UCLA).
