If it weren't for the fact that he's getting David Carr'd out there, I'd still like to see him perform with a little time. Beckham is double covered on almost every play. That means Eli has to look off him to let his route develop. By the time he does that, the rush is on him. The rest of the stuff, tipped int's fumbles, inaccuracy- that's been going on his entire career.
A QB who's a threat to run can hold up 1 or 2 rushers whose job it is to protect the outside. I'd say this is 75% on the Oline
