Jordan Hill is young and broke his hip.
Sure, Howard was starting off hurt but Pau hasn't been able to get healthy for more than 3 games the entire season. Blake getting an ab strain is pretty random. Nash breaking his leg is a super rare basketball injury.
I expected missed games of course, but I didn't think there would be this many 6+ week injuries. Lakers have had 5 main guys have 6+ week injuries (both Steves, Pau, MWP, and Hill).
edit: The Lakers would be giving up 135 a night if Dwight was hurt and this version of Pau played C. Howard has actually been very good the past month or so on defense, even more so of late. But everyone else is getting worse and MWP was the only other defender worth a shit. Hes obviously a LOT healthier now. His defense is so active and covers so many mistakes. But the Lakers make waaaaaaay too many mistakes (Kobe, Clark, Pau especially right now) that he can't do it all.
