As I recall, Wells didn't seem to have much in the way of injury issues as far as missing games, until he joined the Rams.
Either way, while the OLine strategy may have been a risk, they couldn't fill all holes at once. Earlier draft choices on OLinemen probably would have cost them defenders who are playing a role in making the defense pretty good today, thus shifting the deficiency and thus complaints I guess.
And sorry, but we must not be watching the same games because with the exception of the Packers game, while the protection hasn't consistently been good (and no QB enjoys such luxury), Foles has had time to make plays but simply has not. He's locking in on one (maybe two targets at best) and missing guys that have been open. His accuracy has been questionable at best. And the WRs who beat defenders deep typically have to wait for his downfield floater to finally get to them. And OMG, has he thrown someone open or hit a timing route yet?
I'm hoping for improvement for all on offense, but the real key is Foles. It's just the nature of the position.
