I hear ya, but I disagree with you.
Because I've been watching this kid since his Georgia Tech days. I knew his skill set coming into the league. And his skill set is (was) superiors to Mendy's.
1. Dwyer hits the hole..Mendy dances and studder steps
2. Dwyer runs through arms that reach out for him...........Mendy gets pulled down by fist tackles
3. Dwyer doesn't have negative carries....Mendy studders, dances and gets tackled for losses
4. Dwyer doesn't fumble....Mendy fumbles at the most inopportune times
The only thing that Mendy does have that is better then Dwyer is the straight speed. But that isn't enough to make him a better back then Dwyer.
Prediction: Mendy won't be resigned next year because of the emergence of Dwyer. That will prove who management feels is the best runningback.
