Go West, old men!

Amar’e Stoudemire stayed in New York for another impending knee surgery as the NBA’s oldest, most fragile title contender flew West yesterday. The Knicks embark on their long-feared, five-game, eight-day West Coast trip, opening tonight against Stephen Curry and Golden State.

Stoudemire is out for the regular season and may not be back until the second round of the playoffs, if the Knicks get that far. Carmelo Anthony is highly uncertain to play tonight, listed as questionable, possibly missing his fourth straight game with a sore/stiff right knee. The good news is the Knicks have not announced that Anthony needs surgery, too. The better bet is Anthony will be ready for Wednesday’s homecoming in Denver, where he played the first seven-plus seasons of his career.

This Knicks’ traveling road circus — and they are built on stilts — is lacking star power. They have more concerns than just the Pacific time zone as Mike Woodson has to again re-jigger rotations.

To escape the west without getting massacred, the Knicks (38-22) will need vibrant 3-point shooting from Steve Novak, consistency from J.R. Smith and throwback defensive performances from Kenyon Martin. And perhaps Anthony will return with the same defensive mindset he had earlier in the season when the Knicks were streaking without Stoudemire.
