I've told you before, however, I won't say it again (or again or again or again...), I'll just copy and paste my Cowher Manifesto.
However, I will say this... it's not that "nobody wants" Cowher, it's that he's waiting for the Giants job to open to come back to coaching or he's not interested. If fucking Norv Turner can have three coaching jobs in this league then I'l bet the bank there are a ton of teams who'd love to have a coach like Cowher.
