I'm pretty confident that the As are going to want Frank Thomas DHing as much as they can get him there.
edit: Oh, I see what I did. I meant above that Johnson will split time at 1B with Swisher and DH with Thomas. I'd give Johnson 100 starts at 1B, 30-40 at DH, Swisher 60 starts at 1B, 80 starts in RF, and Payton the remaining starts in RF as well as some in LF.
Or something like that.
