LeSean McCoy had already made history before he stepped on the practice field for the first time as a Philadelphia Eagle. As a second-round pick, the 53rd overall selection in this year's draft, McCoy was chosen with the highest draft pick to ever be used on a running back in the Andy Reid era. Not even All-Pro Brian Westbrook, a third-round selection, was drafted that high.

The need for depth at the position in the off-season was apparent. Correll Buckhalter departed for a chance to start in Denver. The only other running back on the roster with experience in the Eagles offense was Lorenzo Booker.

"We drafted McCoy, obviously, for a reason, and that's to work in and play," head coach Andy Reid said. "And so, I think what I've seen from him, and these camps are good if you're looking at the skill position players, you get an idea of what they can do and see what their strengths and weaknesses are there. I like what I've seen from him."

So, what has he seen?

"Great change of direction, ability to catch the football." Reid added. "We're asking him to do a lot of things formation-wise; he's able to handle that. He wants to learn, and has enough aptitude to learn. And so, he's really done well."

The question now is how long is it before McCoy is expected to make an impact on the offense. Westbrook underwent ankle surgery earlier this month and the Eagles are optimistic that he will be fine for the start of the regular season. And as good as McCoy looked in the Organized Team Activities, he will need to prove it with the pads on during training camp and the preseason in order to earn playing time.

"It's hard to talk about whether I'm going to play immediately if I don't know what I'm doing," McCoy said. "We have to get that squared off first then further down the line we'll know more about it. I'm doing pretty good I think. Everyday I'm getting better and better. Fewer errors, especially mental errors."
