07:26 AM ET 10.25 | For now, there are a few cracks in the optimism for 39-year-old Steve Nash's strong start to the season. With the regular season set to tip off in less than a week, some of Nash's teammates are starting to wonder when, or even if, they'll have the full services of the surefire Hall of Famer in their lineup this season. ... [Mike D'Antoni] said Nash was able to make it through a full practice Thursday but cautioned that he could hold Nash out of the preseason finale Friday in Anaheim. If Nash doesn't play Friday, does he think he will be ready for the regular-season opener Tuesday against the Los Angeles Clippers? "I do, I do," Nash said. "I played the last game even though I probably shouldn't have, trying to get a little extra rhythm and some reps. By the end of the week, I should feel better."
