This guy is obsessed with the fumble recovery rate, which I've never even heard of. Seems like a random thing to be even a small basis for determining a team's success. It's about as arbitrary as the dropped passes using two hands rate.
(I would say, however, that with a more aggressive DC, and heavier reliance on the run, and a quarterback who can throw accurately, which we appear to have, our FRR, as I'm dubbing it, should improve massively.)
We will see a different D. Wannstache could be the worst coordinator ever. And with a new QB, and an army of speedy wide receivers, and using Spiller and Jackson to their full ability, anything is possible.
