Peak 8 wins?
They won 11 with Bridgewater throwing 14 TD's and 9 INT's last year, I'm fairly certain Bradford can manage something similar to that. Barring further serious injuries this at least a 7 win team with upside of 10 or 11.
At any rate, yea, it's a nice trade in a vacuum, but if Wentz goes out there, takes a beating and never fully recovers because he's forced to go in before he's ready then this trade will be an underrated reason for him not evolving into what they hope he can be.
And Chase Daniel is not as good as Bradford. The difference might be negligible, say maybe a 7 win season with Bradford and 5 with Daniel, but 2 wins will make a big difference as far as when Wentz comes in.
