I agree with wcbsas. Callahan is a good grinding position coach, and will help my Cowboys run the ball, but he is not a credible Head Coach and has flopped twice as the top dog.
If you want some proof, just watch how bad the Jets offense will be this year without him. The Jets could always run the ball even with Sanchez's pitching woes. The reason is BC.
I'll gladly take BC back as our o-line coach and let Barney go.
BC is a line genius, and the SOB could recruit!
I'm not sure why you think Callahan is a line genius. There were only two teams in the NFL last season that averaged fewer yards per carry than the New York Jets (only 3.8 ypc), and they ranked 22nd overall in rushing yards per game. They weren't much better when it came to sacks allowed, ranking 20th in the NFL. You'd think an offensive line genius would at least be able to finish in the top half of the league in some categories.
I also don't know why you think he was a great recruiter, or any more special than the people we have on staff now.
The man left our beloved football program in complete disarray, and you would take him back as a replacement for ANY staff member? The ONLY position I'd hire him back for would be to sell Runzas at the stadium. And only because I don't like Runzas. Because he'd probably screw that up, too.
