Yes and no.
Yes, the offensive line is not the best in the league. These guys have a long way to go, but the makings are there for a productive O-line. This offensive line, with a healthy Marc Columbo, will be able to compete at the professional level with the best of them.
As far as the recievers, we don't have a winner in the bunch, that I'll agree with. If your getting covered, you break route and work your way back to the ball...pop warner football will teach you that.
Now...the big But.
Watch Peyton Manning work just one drive down field. He goes through his wide reciever progression perfectly. One, Two, Three, BALL. He gets back there, he is decisive, and he gets the ball off quickly.
Now, comparing any offensive in the leauge to the Colts may be unfair, but much of the blame lies directly on the shoulders of both Quinn and Krenzel. As a high school quarter back, I learned that you are "not" as good as your recievers are, you should still make plays and get the ball off quickly. Those two spend way too much time in the pocket, behind an already questionable o-line, and then make bad decisions with the football. That is not a winning combination.
