In all honesty as much as I love seeing him in a Red Sox uniform, Mookie Betts is replaceable. Likely not with someone as capable as he is but someone not so bad that it would limit the team that much. If prevailing wisdom is that we are going to be so poor in the next few years, that we won't be able to compete, what sense would it make to even consider a long term signing? None - with that thought in mind, he should be traded for a windfall of potential talent.
