really depends on a number of factors such as is it a keeper, dynasty, or redraft league? how deep is your RB position? etc. right now i own him in my dynasty league, and after completing a deal for s jax last night, parker is my number 4 rb behind AP, gore, and jax so in my particular situation i'm not dropping him yet. i also have mewelde, shonn greene and chester taylor so parker is my only legit non-handcuff backup. but if its a redraft and willie is your #5 back, drop him for sure. parker is tricky because turf toe is a lingering injury, but pitt has an unbelievably easy schedule against run defense's until the week 16 championship vs balt. bcuz he's only a year removed from having a 1300 yd season, i would hang onto him unless this injury lingers another 3 weeks and/or mendenhall continues to put up 100+ yd games.
