I wouldn't take Dunn over Dunn either!
I don't really get a measure of a player via RBI. Only his place in the batting order and the rest of his team. Seeing the other stats are nice but as far as getting a good idea at how likely a player is to produce a run, OPS works for me.But when you begin to get a statline, even one flashed on the screen while watching baseball games you can get a pretty good understanding of a players game. If during a TV game they broadcast AVG, OBP, SLG, RBI, HR you can get a pretty good picture of a player.
