Feel like the team had to have underestimated Grichuk if they were trying to bring in Brantley. IMO, Grichuk is the best player of the three, his power numbers are a bit higher than usual, but he's been more than serviceable his entire career.
If I recall his walk up song was Dirt Road Anthem. Not a classic or anything, and maybe a bit embarrassing but it played well in the ballpark, especially on the Friday night games.
