I am playing in the Astrodome, focusing on pitching and defense. I currently have Driessen, but Joyner is available. Driessen walks more, has more speed, and makes fewer errors (2e7). Joyner gives me a 1e10, with no stolen base potential, fewer walks, but a higher slugging pct. His BP HR's are not overly pervasive (though the Dome hurts everybody except singles hitters). Joyner is also better at moving up runners than Driessen.
Driessen better fits my philosophy of running, but Joyner (hopefully) would give me a more dangerous bat in opponent's parks, and would still be able to bunt/H&R in the dome (as well as more extra base hits). He was a line drive hitter, which is reflected in his card quite well. I'd be sacrificing OBP, though (depending on the year I get).
I'm truly conflicted, but favoring Driessen at this point. How has he or Joyner fared for you guys?
