Read? It was Man Coverage. Inside leverage, do NOT get beat to the inside. Plax faked the Slant, and Hobbs has to honor it, or it's six that way, too.
It was a sell out blitz by Pees, and it hung Hobbs out to dry on Plax. Great call by the Giants and a bad one by the Pats. The blitz doesn't get home, and Eli just tosses it up.
Where's the mental error?
I'm not a big fan of Hobbs, I don't think he should be starting on this team but in regards to the final play on the Giants drive you're right, that was a terrible play call not Hobbs fault that resulted in the TD.
