Possible, but hardly a terrible decision. Doing so allows for another shot at a player better suited when the big leagues around the world are between seasons which boosts the available players out of contract or teams willing to part for the right price.I'll be the one with the contrary opinion.
Would be a terrible decision by them. Give the guy a season to get acclimated! Maybe it never works, but if you liked the guy 6 months ago you should give him a chance to get through a season before pulling the rip cord.
