We’ve all been hearing how Tim Tebow, despite his extraordinary success at the University of Florida, may not be that hot a pro prospect. Until now I just flat didn’t believe it — I felt pretty certain that the naysayers are going to get their comeuppance — that Tebow’s leadership and learning skills and work ethic would carry him to success in the NFL. After watching him in today’s Senior Bowl, now I’m not so sure. He looks slow; awkward; tentative — he telegraphs where he’s going to throw it, then he winds up and releases it so slowly that the defense gets a jump on him. So how come this wasn’t apparent to me while watching him at Florida? Was he surrounded by such a great supporting cast that his deficiencies didn’t show?
