Polk is their short yardage solution and maclin looks like a top 5 wr in the league right now. Sanchez looked competent, I'd probably roll with him rest of the year and draft a qb.
Sanchez was nice filling in today, and he does have experience of making it to 3 afc championship games, but I'm scared as hell with him under center for the duration of the season.
Foles ... he may be missed.
