Baserunning, sure. I'll give you that.
But this PREMIUM DEFENSIVE POSITION REPLACEMENT LEVEL crap has to stop. Any player who can hit like Abreu holds tremendous value, I'd go so far as to say unequaled value. Abreu is the only player, regardless of position slugging above .600. Not only that, he's the only one even close. He's the only player in baseball that has even a remote chance of an OPS over 1.000. He leads MLB in wOBA and WRC+ too, lack of baserunning and all.
It doesn't matter what position Abreu plays, he is cramming much more offense than anyone else in baseball into one spot in the lineup. There are plenty of teams that are not getting Abreu like production out of their 4 and 5 hitters combined (totally unverified claim). Don't give me the "well you see Trout plays center and the average center fielder can't hit near as well as the average first...", Abreu so far out classes what anyone in baseball does with the bat arguments over positional semantics are worthless.
