Maybe the change of manager/venue has helped Patterson, or maybe he's starting to come of age where everything is working for him all at once. Clearly, as a base-stealer, he and Roberts (who I'm also happy to own) have the green light and seldom get caught.
Many of the guys who don't like Patterson are bitter Cubs fans and who can blame them? If I had a guy who played for my team who suddenly went nuts on another team, I'd feel that way, too.
As far as CPat, I think he could go 20-50 no problem. He's already better than halfway there on the SB with less than half the season under his belt. My projection for him: .275, 19 HR, 78 RBI, 58 SB. I think most people would take that from an undrafted FA.
