My first prediction is that Jeter attempts to return sometime in Mid- May but not as an everyday player at first. He loses another step or two defensively and on the bases and the talk starts about what to do with him by late June. He re-injures his ankle in July and announces his retirement.
Andy Pettitte has a solid first half of the season, making people think he has found the fountain of youth. However, he starts to slow down by late July and hurts his arm during his first start in August and is done for the year...announcing another retirement.
Texiera re-injures his wrist during rehab in Tampa and needs surgery...done for the year.
A-Rod doesn't return until August and is mercilessly booed even louder than before, even in Yankee Stadium. By late September the Commissioner's office announces a 50 game ban for PED use.
