Plus Jeter, maybe Arod, and like 5 others too old to play the field.
That's just crap.
Jeter, Ichiro and Wells cannot play the field every day. Beltran's knees are arthritic an degenerating rapidly, so he'll need to be spelled, too. If Rodriguez doesn't get suspended (and given that it's gotten out that MLB violated state law in its investigation, he's got a hell of a lawsuit if they do try to hand one down), he's certainly not an everyday fielder anymore. It's also pretty crazy to assume that Teixeira will be able to stay healthy, too.
There's going to be a multi-headed monster at DH this season.
