The with the signing of quarterback Tim Tebow, who will join , , and as the ' quarterbacks. If there is any truth to the ' rumored interest in drafting Oregon quarterback , who coach Chip Kelly coached in college, it should be unwavered by Tebow's presence. Here are three reasons why: 1. Roster longshot Unle s the are convinced Tebow will make the 53-man roster this fall -- -- there is no reason for the Tebow signing to affect any of Kelly's draft thoughts. As much as Tebow's name recognition might resonate, he'll be in no Bryan Bickell Jersey better position to make the club in training camp than if Kelly had just signed an anonymous offensive guard who barely made the transaction wire. Moreover, Tebow will be competing with Barkley and Kinne for a clipboard. Mariota would be competing with for starting snaps. 2. Quarterback only? On his way out of the NFL, from the to the to the , Tebow always maintained that he was only interested in playing quarterback. But after two full seasons out of the league, it's fair to wonder if he'll be more flexible with his second shot at the NFL. If Kelly is entertaining any thoughts of trying Tebow in a different role if he doesn't win a quarterback job, that's all the more reason to make no April a sumptions about October impact. And by extension, all the more reason to draft without consideration of it -- whether that means a big move for Mariota or a seventh-round flier on a quarterback sleeper. 3. Money not an i sue Tebow's contract reportedly will be for the minimum one-year salary, which he'll have to make the team to even earn. So beyond whatever minimal bonus might go along with that, the have no financial stake in their newest quarterback. And thus, zero salary-cap concern when the draft comes around. Bradford has just one year left on his contract, and the rest of Philadelphia's quarterbacks aren't expensive, either. Conceivably, a Mariota deal could be the only quarterback contract of significance on the roster by 2016. *Follow Chase Goodbread on Twitter * . Cm Punk Jersey
