Our system heavily favors the TE position, especially running out of a two TE position.
Payton is all about match-ups, three wide, power formation, single back with two TEs, five wide, multiple motion... Crumpler is tailor-made for this offense -if he can get back to his pro bowl level.
I wouldn't sign Leftwich, though. He has a slow release that is exacerbated by his long wind-up, and he is injury-prone.
I'd like to see the Saints make a run at Josh McCown as a back-up to Brees. He strikes me as someone better suited for this offense.
