Wow, another "if" guy. Great if Colon works out. If not, join the massive scrap heap outside Jet Central.
The thing is Borgo at least these "if" guys have some potential and are coming cheap. Cheap low cost fill ins while you build. You need to cover your bases by filling some holes before the draft. Both Landry and Bell were big if guys last year.
Since I didn't watch the Steelers much, I did a quick google to find any grading on him:
"Pro Football Focus graded Colon as a top-15 run-blocking guard and top-25 pass-blocking guard in 2012, but charted him with the most penalties in the league at the position. Turning 30 in April, Colon figures to replace Brandon Moore as the Jets' starting right guard. New York now has four starting offensive linemen in place: LT Brick Ferguson, C Nick Mangold, RG Colon, and RT Austin Howard."
