they don't know what it is until the MRI...strain is just a generic term to keep the media and fans at bay
Yeah, unfortunately this is true. Bynum's injury was originally called a "right knee strain". Ugh.
Yeah, but KG was able to put weight on it immediately after the injury (only for 1 step, and he didn't want to do it again, but the knee held) and was moving fairly normally at halftime warmups. There's no way this is as bad as Bynum's injury.
I lean towards what others are saying - KG's had problems with the knee all year and it caught up with him. He hadn't played in a real NBA game in a week, and when the body hasn't experienced that kind of high-intensity, high-impact movement in awhile, bad things are more likely to happen.
