With Tim Tebow now at least temporarily ensconced in Philadelphia, everyone's kind of settling in to see how Chip Kelly and the Eagles handle this and how Tebow deals with playing for a new team.

If he wants to make the team succeed, he better have become a better practice quarterback than he was with the Broncos or Jets. To wit: former Cardinals kicker Jay Feely told Jim Rome on Showtime during this Wednesday's episode (airs at 9 p.m. ET) Tebow is the "single-worst quarterback I ever saw."

"He's such a dichotomy for me. Because I really respect the person, the man, the things that he believes in and the things he does off the field," Feely said. "He was the single-worst quarterback I ever saw in my career in the NFL."

Feely then proceeds to tell a story about Tebow warming up and losing ... to air. 

"I watched him one day ... I sat and watched him do routes on air with Ken Whisenhunt as we were playing the Broncos," Feely said. "And routes on air, there's no [defensive backs], you know exactly what he's going to run, there's no pass rush. He had like 13 incompletions on routes on air. Jim, you and I could go out and do routes on air and we would complete most of our passes."

Brutally hilarious. It fits with everything you hear about Tebow in practice too. Not that Tebow's game completion percentage is particularly stunning (47.9%, which actually is stunning but for the wrong reasons). 

Feely's take on the signing is that Kelly really believes his system will overcome everything and manage to "utilize" Tebow.

"He thinks his system is better than everyone's and his system is gonna work and it doesn't matter if he gets rid of star players like DeSean Jackson or LeSean McCoy," Feely said. "He thinks he's smarter so he can take a guy everyone else has quit on ... and utilize him."

Time will tell but the odds are definitely against it happening.
