Agree on the no-trade thesis. As for the lost cause part, you could also be right. Ortiz went through a pretty big slump the season after Manny left or the one after that. In fact, hitting-wise, it might be the best Sox outfield in recent memory.
But, as oldtimer says, this is a business, and right now JBJ on the active roster is a bit of a liability because his hitting right now is actually worse than in 2014 when he claimed the centerfielder job after Ellsbury left and JBJ ended up in Pawtucket.
Do you remember that season? It's the one immediately after winning it all with Ellsbury in CF--you know, the Ellsbury who could hit, but not like the one who hit in 2011, and had wheels and was a decent centerfielder despite a weak arm. I would argue that right now Benintendi is pretty darn close to that Ellsbury, but the JBJ loyalists persist in saying that, compared to JBJ, he is an unmitigated disaster in CF and of course conveniently ignore that he can hit and get on base and contribute to the offense and is probably close to Ellsbury in CF in 2014.
So my thought is that sending JBJ down, if it is still possible, is the right move for him and the right move for the Sox because, contrary to the beliefs of the devout JBJ loyalists, an outfield of JDM, Beni, and Betts would actually be pretty darn good.
