The U.S. national basketball team plays its world championship quarterfinal game tomorrow against Russia; the height-deficient Americans’ main challenge will be guarding the Russians’ twin towers, six-foot-eleven-inch Sasha Kaun and seven-foot-one-inch future Knick Timofey Mozgov. Mozgov has been scoring efficiently for his squad while blocking a shot per game, good news since those are the two things Garden fans hope he’ll be doing off the bench next year for the home team. (Even if Amar’e Stoudemire made his impact by not playing in Turkey, you’ve got to count it as a win for the Knicks that two of their off-season pickups have had prominent roles in determining the outcome of the world championships.) In other news, both Fran Fraschilla and stat guru Wayne Winston think that the U.S.’s most likely opponent should they make the finals will be Turkey. (Pre-tournament silver-medal favorite Spain got knocked off this morning by Serbia.)
