Playing Trout in Left Field saves his legs and means he's less likely to run into a wall at speed. I love Bourjos, but I know who's expendable and who isn't. Regarding keeping Trout-he'll play for the team that offers him the best total package; money, chance to win, Turf, etc. Left or Center isn't going to be a consideration when he's a free agent, only who treats him the best.
