PHILADELPHIA -- For the first time this week Eagles head coach Doug Pederson allowed for the possibility that rookie quarterback Carson Wentz will not be inactive for his first full season but reiterated his place as the team's No. 3 signal caller.

On Thursday we might have found out why.

According to ESPN NFL insider Adam Caplan, the coaching staff has already made a tweak to the North Dakota State product's throwing mechanics after an altogether impressive yet inconsistent showing during spring OTAs and minicamp practices.

"They're not even thinking about playing Wentz this year," Caplan said Thursday on 97.5 The Fanatic. "It's about get him ready. Get him comfortable. Get him understanding the pro-speed. Remember, yes, he played in a pro-style offense, but that was Division 1-AA. This is a major jump.

"He needs to work on his mechanics, as I understand it. Footwork, shoulders square and the other thing is, the way he holds the football had to be adjusted a little bit. I'm not saying he won't play, in fact, my prediction is he'll start 4-6 games."

Caplan's revelation is the first time that we've heard of real, tangible adjustments of Wentz's game that have been made by the coaching staff and could explain some of the wobbly passes on deep balls throughout the spring.

On the practice field, Wentz has all of the trappings of a franchise quarterback. Big. Mobile. Plus-athleticism and arm. However, there were several throws that seemed to flutter out of his hands, but impressively enough, he would rifle off several passes thereafter that seem to reinforce why the Eagles moved up 11 spots in the NFL Draft to choose him.

While some have questioned Pederson's apparent reluctance to either Move Wentz up the depth chart ahead of veteran backup Chase Daniel or open up the quarterback position to a full-blown training camp battle, Caplan says that he believes the first-year head coach is handling this somewhat tricky situation in the best way possible.

"He did a smart thing," Caplan said of Pederson's comments. "Sam Bradford could get hurt. Chase Daniel could replace him and not play well. Maybe Sam Bradford later in the year isn't playing well and needs to be replace. Doug did a smart thing. What he's doing, is covering all of his bases and look at every possible scenario. He's not going to tell you what those scenarios will be. When I thought about it, Pederson's comments made perfect sense."
