Everyone and their mother has an opinion on Tim Tebow's return to the NFL. But few people (and few mothers) know Tebow as well as Champ Bailey. The retired Hall of Fame cornerback, who spent 10 of his 15 seasons with the Denver Broncos, called the former quarterback his teammate for both of Tebow's two years as a Mile High signal-caller. On Wednesday, he joined CBS Sports' All Things Covered podcast, co-hosted by Patrick Peterson and Bryant McFadden, to offer his perspective on Tebow's sudden march back to the gridiron.

"He's infectious," Bailey said. "A great leader. I love his preparation. But I grew up with a lot of guys like that and they just didn't have enough athletic ability to play football. He has a lot of great qualities, but he's just not an NFL quarterback."

This, remember, is coming from one of the Broncos' top players during Tebow's short-lived run as Denver's QB. From 2010-11, Tebow captivated all kinds of fans for his tendency to start slow, play QB with unorthodox mechanics, but then turn it up in crunch time with a slew of comeback wins. However, Bailey is convinced Tebow's move to tight end -- where he'll attempt to make the Jacksonville Jaguars this summer -- should have come way back when he was still under center.
