No matter the year, the New York Jets had one sure thing week after week: Curtis Martin. Now that he is out for the season, nothing is so sure anymore. Will Martin return to the New York Jets in 2006? If he does, will he be the starter? Martin vowed to be back in 2006, and coach Herman Edwards said Monday he anticipates the venerable running back will be on the team. Many questions have to be answered first. When training camp opens, he will be 33 -- ancient in running back years -- and coming off surgery on his right knee. Even before he got hurt against Miami in Week 2, there were questions whether he lost a step just one year removed from winning the NFL rushing title. But his supporters point to one key fact: Martin played most of this season with a major injury before deciding to call it quits.
