Watkins appears to be much better in zone coverage than man-to-man as he still seems to get turned around a bit too easily by opposing receivers. And Roy for the oddest reason seems better in man-to-man than in zone. I wouldn't doubt if they are looking to keep Parrish around more for next season to have him compete with Watkins at FS. And if Watkins does well and he plays pretty well, we could move Roy to the LB spot in the nickel. We reportedly looked at Roy as an LB in the nickel early in training camp, but my guess is that they didn't feel comfortable with Davis and Pile having to be the safeties.
I don't know if Zimmer would want to pull this off, but if we get Crennel, he did use this with Rodney Harrison in New England. Not at the rate that Polamalu does it with the Steelers, but they still did it.
