Very good question and one I meant to address in the article but it slipped my mind. It’s unfortunately a question we do not have a lot of data to give a complete answer to though.

The difference in WAR’s positional value for a LFer and a 1B through 150 games is roughly 4.5 runs. I have Morrison as a -2.5 1B, so if we assume his defense stays static in a move to LF, that would make him a -7 defensive LFer. Morrison has well below average range, but as you point out he has a very strong arm.

I think -7 is a solid estimate for his defense in LF, maybe along the lines of his range being -10 runs and his arm being worth +3. However, with just how important range is to the OF, I imagine it’s more likely he’d be under -7 rather than over. It’s hard to give a concrete estimate though.

With 1 run equaling 0.1 WAR, it’d require for him to be a -4 defensive OFer for his projection to match Dominguez’s (+1 if Dominguez can be +10 like the scouts believe). It’s possible, but I find it unlikely.
