At a time when it wasn’t clear whether quarterback Tim Tebow would return for a fourth season at Florida or take a chance on the NFL draft, Tebow cleared up any confusion on Saturday night.”I’m coming back,” Tebow told a crowd celebrating Florida’s second National Championship in three years. (In the season that didn’t end with Tebow toting the BcS Trophy, he hoisted the Heisman instead.)On Saturday, ESPN’s Chris Mortensen reported that Tebow’s competitive juices had been aroused by the contention that he can’t be a successful at the next level. Mort said that Tebow has been told that he could be drafted anywhere from the bottom of the first round to the third round.Though, on one hand, Tebow might improve his draft stock in 2009 (if coach Urban Meyer incorporates from pro-style features into the shotgun-heavy spread offense), his decision undoubtedly will fuel questions as to whether truly loves the game enough to try to compete at the highest levels.Such concerns arose after USC quarterback Matt Leinart decided to return after winning two national championships and a Heisman -- and they have been borne out based upon his inability to keep a starting job in Arizona that had been handed to him.
