...I think he should stay behind the plate. You got Villalona coming up to play first. Gillaspie will be at 3rd. You could play Posey at SS or 2nd.
This would save Posey's legs in future years, and this group would be a formidable middle of the order down the road. People are saying Gillaspie will be a Bill Mueller type of hitter, but I think he will hit for more power than that.
Put Lewis, Rowand, and Ricardo Rodriguez in the outfield in 5 years, and this team will be loaded. Especially if Lewis learns how to steal bases. JMO.
