- KC Joyner, NFL Insider
Every Tuesday, K.C. Joyner writes up a "Draft Lab" on a 2010 NFL Draft entrant -- this week looking at Tennessee senior defensive tackle Dan Williams. For a full archive of KC's thoughts on various prospects, please click here.
One of the most difficult scouting projects is grading an inconsistent player. When a player alternates between performing well and performing poorly, the issue is no longer a matter of whether or not he has professional-level potential. The question that has to be answered at that point is why there is a performance variance and whether or not the issue causing the inconsistency can be corrected.
I bring this up because Tennessee senior defensive tackle Dan Williams (#32 in Todd McShay's Mock Draft 1.0 and #18 on Mel Kiper's latest Big Board) may be the most inconsistent player I have reviewed in the Draft Lab series.
