Los Angeles Lakers general manager Mitch Kupchak doesn't doubt Kobe Bryant's will or toughness. When the 17-year veteran says he's way ahead of schedule in his recovery from a ruptured Achilles, Kupchak believes him. But when assessing the state of the Lakers at this critical juncture -- after the departure of free agent center Dwight Howard -- the "uncertainty" of Bryant's health remains Kupchak's most pressing concern. "The primary weakness is uncertainty. I don't think that's a secret to anybody," Kupchak said Thursday in a wide-ranging interview with Colin Cowherd on ESPN Radio's "The Herd." "Our best player, one of the best players ever to play the game, is recovering from an Achilles tendon tear and one of the other all-time best, Steve Nash, ended the season injured. "Steve, to my understanding, is close to 100 percent, but he's not as young as he once was and Kobe's a big question mark. We're very optimistic, he's getting treatment every day, he's in the facility right now, but he hasn't been on a basketball court. Uncertainty going forward, I guess with our health status would be the biggest question mark." Read more http://espn.go.com/los-angeles/nba/...akers-gm-does-not-doubt-kobe-bryant-toughness
