Too lazy to look it up, but it seems that the vast majority of explosive (30+ yards) plays last year came from Flowers, Mack, and Adams. Mack and Adams being gone could very well be an issue. There was more to them than their 40 time. Mack had great vision, and there was a noticeable drop-off when he wasn't in. Adams ran hard, and was great on the jet sweeps. We may have guys that have similar 40 times, but that doesn't necessarily mean that we can plug them in and get the same results. I suspect there will be a slight drop-off in explosive plays, and the overall effectiveness of the offense. We'll find out soon enough.
