Back to the thought of trading Jackie Bradley.
Even if he only replicates his 2018 hitting, he will well be worth having on next year's team. His fielding is superior in center field, he allows Betts to be in right field, he is at least a very good #8 or 9 hitter in a contending team's line up, he is not likely to bring back as much as he is worth, and has been a very solid citizen in the Boston community.
Bradley is a top level athlete who will hit much better than he has to date if he learns to keep his head still when swinging in every at bat. Watch his at bats when he is doing well and when he is in a slump and you will see what I am talking about. His head jerks to the first base dugout when slumping and stays right on the ball to contact when hitting well.
