Maybe but you can just feel the offense flowing better with the changes. Also his expereince brings value in and of itself. For example showing Brenner the fracture in the OL and how to fix it against The Rats. Thats something Martin definitely would not have noticed.
McKinnie has allowed 5 sacks, 7 hits, 18 hurries IN ONLY 8 GAMES
Martin allowed 7 sacks, 7 hits, 15 hurries in 7 games...NOT A HUGE DIFFERENCE
