FWIW, last year Celek played 880 snaps, caught 57 for 650 yds, 1 TD, 2 passes over 20 in 4 tries, and had 8 drops (all over the middle). He graded out below average in run and pass blocking, as well as a receiver. Can't see trading for him.
I'm thinking we go with what we have.
1. Did you see how bad the Philly line situation was last year ?
2. Celak is a better blocker than Keller was
3. He would be a red area target
4. I would not trade 1 thru 4 pick for him
