Chadman used the green colour to highlight "good stats" & the red colour to highlight "bad stats".
Ramon Foster's stats need to be viewed slightly differently (same with Kemo really) as both played less snaps than the other players mentioned.
Of particular concern is that Justin Hartwig is at the top, or near the top, of every catagory for "bad stats" for the Center position in the NFL.
That said, Trai Essex didn't fair much better at OG.
Interestingly enough- our OT's were neither great or bad in most stats. Willie Colon graded out 3rd overall for OT's on this site in the NFL. Maybe the FO are right in their assessment of Willie?
