Florida quarterback Tim Tebow struggled during Saturday night's Senior Bowl, but said after the game that he's "open" to working on his fundamentals. Tebow looked shaky running a pro-style offense and fumbled twice in the South's 31-13 loss to the North. "I think I'm definitely open to improving my fundamentals," Tebow said after the game. "I think I definitely showed that by being here. If you just watched the way I played, you could see there is room for improvement and what I need to work on."
