According to ESPN's Shams Charania, aka the Harbinger of Bad News these days, Stephon Castle will be re-evaluated in 1-2 weeks after an MRI revealed a hip flexor strain. Fans already knew that Steph wouldn't be playing in tonight's game against the Memphis Grizzlies, but the injury designation said "hip flexor soreness." Unfortunately, it's actually more than that, and once again, San Antonio will have to adjust.
The worst-kept secret is the "breakout season." It's used too much now and generally doesn't happen in a player's second year because they're still learning so much. It sounds like I'm complaining about it, but I'm not.
