When the New England Patriots signed headline-grabbing quarterback Tim Tebow there was no question there would be a lot of buzz around him in training camp. Tebow draws a lot of attention wherever he goes but unfortunately for him it’s generally not because of his play on the field but more as a result of his outgoing personality and the very public way he exercises his Christian faith.

Tebow’s struggles to develop into an NFL caliber pocket passer are well documented. He’s in his fourth year now and thus far he’s had little success transitioning from a mobile college quarterback to a consistent NFL signal caller. In the one season Tebow masqueraded as a starting quarterback his numbers were dreadful. He completed only 46 percent of his passes and sported a pitiful quarterback rating of 72.9. If there were a Mendoza line for starting quarterbacks Tebow might be its namesake.

Tebow’s a likable guy and there’s no questioning his competitive spirit on the field but to believe he’ll develop into someone coaches can trust with their team’s offense every Sunday is unrealistic. The Patriots have a world class coaching staff. There’s no debating that. To think however that they will succeed where all others have failed is a reach. It’s not like Tebow was working with bad coaches on his previous teams. John Fox and John Elway in Denver have pretty impressive resumes. When in New York Tebow worked primarily with offensive coordinator Tony Sparano and quarterbacks coach Matt Cavanaugh both well respected throughout the league. Josh McDaniels is a great coach and he obviously saw something in Tebow when he drafted him that lead him to believe he could develop the young quarterback into an NFL starter. Now that Tebow has had the opportunity to play elsewhere it’s worth wondering whether McDaniels still believes that.

It’s not Tebow’s accuracy as a passer that will ultimately determine whether or not he makes the Patriots roster out of training camp though. It’s more the fact that the Patriots simply don’t need a third quarterback and with so many question marks at so many positions the opportunity cost of keeping Tebow on the roster is too high. With so much competition in training camp at so many critical positions the Patriots are better served using a roster spot to carry more depth at a position of uncertainty than on a third string quarterback who will never see the field.
