You nailed it on the head. Not to mention if they decide to keep Ichiro for a few years, from a marketing perspective, him and A-Rod chasing 3,000 hits can make some extra bank and exposure (not that they don't get enough as it is).
I think Ichiro could eventually go inot the two hole behind Jeter, both those guys excel in the hit and run; Jeter on the base paths and Ichiro makes good contact even with the slower bat. That could help come playoff time not to mention makes the Cano, Tex, Grandy 3-4-5 very dangerous for righties, especially at the Stadium and allows A-Rod to move down to six. Unless ichiro starts batting 9th, he's wasted at the bottom of the lineup. If he remains in the 8th spot, it defeats having him when Martin is a potential double play waiting to happen and doesn't bunt well nor is he good with contact or going the other way so he wouldn't do well with the hit and run. So unless ichiro is on board with batting 9th, he'll have to go to the two hole. Jeter's the better on base guy and Ichiro makes contact and is a good bunter.
