Really the only negative thing that could possibly come out of an OTA would be an injury... and it seems the Eagles may have avoided what would have been a very costly one.
LeSean McCoy left practice today after experiencing some discomfort in his knee. Reports from the NovaCare complex indicate that he didn't appear seriously injured. Jeff McLane caught up with Shady during lunch and said everything looked fine as well.
Just saw LeSean McCoy. Was eating. Looked fine. Said he did something to his knee.— Jeff McLane (@Jeff_McLane) May 20, 2013
It's worth noting that this is just the second time the media has been allowed to watch OTAs and will be the last time until next week. So this likely wasn't the first time a player tweaked, bruised, or knicked something... It's just the first we've heard about.
Either way, it does seem like it's nothing to be concerned about.
