From an NBA story about Warriors forward Stephen Jackson, who says he added 15 pounds of muscle during the offseason, leading to the best season of his career. Sounds a lot like the stories we used to write about ballplayers who showed up at spring training with new found bulk. Given what we now know about them, shouldn't we be approaching stories like this with a little more skepticism? I'm not saying Jackson's dirty, but do we really think the NBA is immune from the PED issue? http://www.mercurynews.com/sports/ci_11917203?nclick_check=1 Jackson was already as brash as they come. Now he has 15 pounds of added muscle, which has also bulked up his ego. The ninth-year veteran — with the help of assistant coach Keith Smart — decided to dive into the regimen of Warriors conditioning experts Mark Grabow and John Murray. It's a big reason he has been playing the best basketball of his career, why he has been able to turn a hot streak into three months of steady production, and why 40.2 minutes per game isn't wearing him down. Strength was never Jackson's strength. Knowing the Warriors would be expecting more from him, he tried something new this off-season. Members of the training staff visited him in Texas, and he hasn't stopped lifting and gulping meal replacement shakes ever since. Lifting a half hour before shootarounds and practices has become the norm... "This is the most I've lifted," Jackson said. "The most I've been in the weight room my whole career. It's starting to pay off. I was thinking that I didn't need it, but as I see now, it's the most I've ever weighed in my life and I still have my speed, so it's definitely helped my game a lot." Said teammate Kelenna Azubuike: "He's like a monster now."
