First, that defensive difference in that small of a time frame is meaningless, as once again, it's too small of a sample to analyze. On top of the fact that yes, he has a good glove, but generational? No. Lin is a perfectly acceptable fielder for the period of time Devers will need to heal up.First he’s much better defensively than Lin because he’s a generational defensive talent, no slight on Lin there. And his OPS is 30 points higher than JBJ, who most everyone on here values tremendously.
Secondly, JBJ has nothing to do with this discussion, and Iglesias has never been a good hitter whereas JBJ has.
