I think it is safe to say that Brett didn't have the season that we were expecting from him, after 150 terrific at bats in 2011. We were expecting a bit much from a 22 year old, but then he came up short too. FanGraphs had him at a 2.9 WAR, which really isn't bad.
Brett has some maturing to do (don't we all), and he runs the bases like he doesn't understand that the other team can tag him out. Maybe John Gibbons will be a good influence. Maybe Chad Mottola will be good for him. Maybe he'll improve as he moves towards his prime years, like most young players do. Hopefully all of those and he'll be great.
I have little doubt that Brett will grow into a star, but I'm not expecting it to all happen this year. His number's till now:
