On point with what GP said, I'm thinking with the extra PA he racked up, Rollins hit for 30 HR, for a guy whose power ceiling in general lies in more of a 20-25 HR type. Seemed like a good deal of his HR's came with a late-season surge if I recall correctly. Still, I'd think Rollins could be good for a 25 HR, 35-40 SB campaign. I'd be skittish to take him in the late 1st round, but if you pair him with a slugger such as Fielder or Howard, whatever Rollins contributes is nice to fall back on.
I thought a case could be made for Rollins over Reyes right after the season concluded, but considering that Reyes might have regressed a bit and still posted a gaudy SB total, gives hope that he could improve to the late teens-20 HR plateau. That said, I don't think Reyes is as safe a bet as Hanley especially in H2H, when Hanley has the better frame built for power with the speed to boot.
