Jenkins has talent, he's just not NFL ready. He could have been called for holding on every single pass play against the pats and was burned repeatedly against the skins. Hopefully some of the other guys will get healthy and Jenkins can learn in mop up duty.
Gay is listed as probable vs the Falcons. Porter actually practiced yesterday and is listed as doubtful. Hopefully he will play vs the Cowboys.
