He had a great "rookie" year, playing three different positions at different times.

He's only going to get better with Byrd along side him and more experience...

I agree but the guy play full speed all the time which I agree with but can he stay healthy the whole year. I know the injury he had at the end of the year was a freak accident but he's a hard hitter. Byrd will will help out a lot but a player like Vaccaro you can tell him to slow it down.
