the problem with doing that is if he truly is as horrific as dunn was once he started to lose his athleticism (like mid 2000s), then his bat loses a lot of value. with dunn, you're talking about a guy who was cranking out a wOBA around .390 every season, which was damn near elite, but he was ending up anywhere from a 1 to 3 win player because he gave back so much value on defense. and there's certainly no guarantee that abreu's bat is as good as in-his-prime adam dunn. you can get as much value in LF with a platoon like schierholtz/hairston at a fraction of what abreu is likely to cost. to me, the only realistic option if you sign abreu is to turn around and trade rizzo. i don't like the idea of playing abreu at 1b and rizzo at lf, because they're both going to leak value defensively, and abreu will probably be a joke in lf (and may not even sign to play a new position).
