Broken noses happen all the time in wrestling, especially in the indies, where WWE has to find its new talent now that they've put all of the other "Sports Entertainment"-style promotions out of business (TNA is on life support). The non-Lucha indies wrestle a much stiffer, more realistic style, as does New Japan, where most of their competitors came from martial arts and some also fought shoot matches in PRIDE. New Japan guys bust each other open the hard way all the time, and I'm sure I've seen Okada, one of their biggest stars, finish a match with a legitimate concussion, something that WWE wouldn't allow now. Where WWE screwed up is letting Rollins keep too much of his indie move set, as the leaping knee strikes aren't a particularly entertaining move and are capable of legit damage, but then again it is his indie move set that got him over in the first place.
The Sting injury was going to happen with any simple bump, as it was later determined that he has spinal stenosis, which is essentially what ended Steve Austin's and Edge's careers.
Raw's ratings are lower now than Nitro's were when they were cancelled by AOL/Time Warner. There is a major lack of star power on the roster right now. Cena is on hiatus. Rollins and Bryan are out with injuries, and from what I've read, the WWE is never going to clear Bryan (concussion related). Orton is out again with his semi-annual shoulder dislocation, and they pay Lesnar $1M/date, so he's never on TV except on the go-homes before a Top Four p-p-v. The good news is that Big Show is also out with a knee injury, so we're spared more Roman Reigns/Big Show main events, which is what Vince would give us every week.
The WWE has failed to produce new stars for several years now, and they refuse to listen to their fans and continue to push people nobody cares about. The fans want Cesaro as a main eventer, but he's a jobber to the stars (and now he's injured too). They have stopped and started pushes for Dolph Ziggler for about five years now. Everybody they bring up from NXT is buried immediately, like Neville, Tyler Breeze, the Ascension, Adam Rose, etc., although most of them suck anyway. Kevin Owens is the only NXT guy who gets any response at all, and it's mostly favorable, which is bad because he's a heel. They will make Roman Reigns the face of their company no matter how many years it takes, and no matter how little number of fans want to see it happen.
The Divas Revolution is a disaster. They bring up three good female wrestlers from NXT, after years of having bikini models in throwaway, 90-second matches, and essentially integrate them with the holdovers by forming three three-woman-teams and having throwaway, 90-second matches. One of the call ups, Sasha Banks, was an absolute star in NXT and should be the face of the division for years, but she is completely lost in the shuffle and just another girl. The result of all of this is, other than sometimes two divas segments instead of one, is that casual fans don't want to sit through women's matches, while the fans that like NXT-style women's matches are disappointed greatly, so nobody is satisfied. And the fact that they have a Charlotte-Paige feud where they miscast the face-heel dynamic, never have a blow off, and then turn the other heel clearly shows they have no idea what they're doing. Or that Vince and Kevin Dunn just think that all women are bitches.
The fact is people will watch good wrestling if it's available. My cable alone has 900 odd channels. and there are subscription channels in addition. The New Japan show blows everybody else away. The ROH show, despite its low production values, is more entertaining than Raw right now. I don't get Lucha Underground on my cable, but people swear by it. NXT does everything right that the main roster does wrong, except for heavily pushing Eva Marie, but that's a side product of Total Divas
