The Pats have tried various techniques in the past, luckily he is made of glass and misses a lot of games. Most recently the Pats had Harrison locked in with Clark, playing a little bit of an OLB / SS combo. This left the Pats run defense lacking and Addai put up good numbers, the Pats will take this all day long. I think they will have Vrabel jam him off the line, pass him to an ILB who will have deep Safety help. I am very interested to see how Mayo / Guyton perform in space with Clark. If they can hold their own the Pats future at ILB looks very good, if they don't fare well, oh, well, back to the drawing board.
