The Philadelphia Eagles and head coach Chip Kelly continued their interesting off-season with another head-scratching move on Sunday.  Multiple sources have confirmed the Eagles signing Tim Tebow to a one-year deal worth the minimum base salary for a quarterback.

Tebow last played in the 2013 preseason with the New England Patriots before being cut.  This signing becomes one of the most questionable in a confusing off-season in Philadelphia.  Chip Kelly adds Tebow to the mix in an effort to bulk the back-up quarterback competition considering Sam Bradford will be named the starter, pending injury.  The Eagles now have depth at quarterback which includes the likes of Bradford, Mark Sanchez, Matt Barkley, and now Tebow.

Tebow is expected to compete for the third-string job against Barkley with Sanchez most likely winning the back-up role after his performance in the place of injured quarterback Nick Foles.

Many experts believe that the Tebow signing is Kelly trying to take advantage of the possibility of a new extra point rule that would require a team to go for 2 after a touchdown, in which case Tebow may be useful.

Tebow has been working hard to make a return to the NFL.  He has been working on his fundamentals and throwing with Tom House.  House is a former MLB pitcher who now a renowned private quarterback's coach.  He praised Tebow for his work ethic, much to the recognition of Kelly.

Either way, Tebow can't be seen as a threat to many other NFL teams.  His lack of ability to read both a playbook and coverage won't help him even if his throwing motion is fixed.
