As long as he hits .425 with a HR every 4.5 ABs with an occasional double thrown in he can strike out 200 times as far as I am concerned.
In the Cubs perfect world Bryant cools off some at AAA while playing an OF slot every day. Then the Cubs can claim they are getting him ready to change positions since they have Mike Olt clogging his ascension to Chicago. It would help if Olt could finally leave his 2 year struggles since being beaned behind and get off to a good start. Then they could either wait for Bryant to show he is comfortable in the OF before calling him up and giving him one of the corner slots. Or if Olt hits and plays third well enough to garner trade interest they could ship Olt out and the call Bryant up proclaiming it the natural thing to do now that they have successfully cleared a position for him to play.
Good chance none of that happens. But almost certainly if Olt gets off to a bad start and then Bryant is called up Olt goes to the bench or has to clear waivers to be sent down. His trade value could drop to nothing.
