When Tim Tebow signed with the Philadelphia Eagles in the offseason, many observers saw the move as just a marketing ploy for the franchise. However, Eagles head coach Chip Kelly believes Tebow has shown improvement in the offseason and that the quarterback has a chance to make the roster.

"I have seen an improvement from Tim since the day we got him in terms of his knowledge of what we're doing, understanding where everybody is. There's a whole process, and for him what we have done is different than what he's done anywhere else,” Kelly told the Delaware County Times. "So in terms of learning our terminology and how we do things, I think each week you've seen an incremental bump in him, so we're excited to see where that takes him and it'll be a good competition as we get into August."

Despite the improvements, Tebow is not expected to fight for the starting or top backup quarterback spots, as those are most likely going to Sam Bradford and Mark Sanchez. Tebow is expected to battle Matt Barkley for the team's third QB job.

Tebow, who played for the Denver Broncos from 2010 and 2011 and New York Jets in 2012, is looking for another shot of playing in the NFL. “I’m just thankful for the opportunity,” Tebow said after he signed an offseason contract with the Eagles. “And I will work hard with every opportunity that I get.”
