Unfortunate injury, let's hope we can tread water until his return. I've heard 6-8 weeks, but knowing Rudy I wouldn't be surprised if he came back sooner. I just hope that he & the team doesn't rush it as we were unlikely to win a title this year regardless. But considering how we (as well as the WC) looked prior to the injury, I think it's safe to say this team has a legitimate shot at competing for a championship within the next 2-3 years (given Gobert recovers, Exum develops, Hayward re-signs, etc).
As much as you hate to see a key player get injured, this could ultimately turnout to be a positive as Booker will get more of an opportunity to increase his trade value, Lyles will get more playing time in order to develop his game, & it will force Snyder to occasionally use Hayward & possibly Ingles at the 4 which will make both more versatile. Obviously everyone was hoping for a playoff run (which is still a possibility) but as long as the injury doesn't have any long-term effects on Gobert, hopefully (like the Exum injury) this is just a minor bump in the road to our 1st NBA Championship.
