Alright I'm bored.
House 1: The GOAT House, but probably not the house you would want to live in. LeBron may be cool at times, but he is definitely constantly subtweeting you and trying to ship you out to another house to get someone else. Ovi might be entertaining but his Russian quirks would irritate you after a while. Tiger is definitely the roommate who sits down next to you on the couch and doesn't say anything for 45 minutes. Trout's personality is unknown. Serena seems like the only normal one.
House 2: The strongest house for sure. Harden might be a bit of a wildcard; but he probably won't be that annoying. Worst case scenario is he just disappears for a week in his room. Federer is awesome and would be a great roommate. Don't know much about Stewart but she seems humble. Zlatan and Shaq would be amazing; super-charismatic and also not criminals and don't take themselves that seriously. The two of them together would be awesome. Just imagine saying that out loud "Yeah me and my two roommates, Shaq and Zlatan are going to play Risk later," it would amazing.
House 3: After hearing a lot of Durant podcasts, I wouldn't be that excited about living with him. He is a strange dude for sure. Mahomes seems okay but the jury is still out. Messi would be like Tiger without the sex addiction; just a blank personality. Rapinoe is definitely sucking people into tense political conversations. Wade broke Rondo's arm.
House 4: My second best choice. Doesn't have the upside of the Shaq/Zlatan house but everyone seems solid. Giannis, Judge and Djokovic all seem like cool, humble dudes and Biles is super nice. I honestly don't know that much about Crosby's personality but I haven't heard anything negative about him.
House 5: No way. We all love Brady, but he would be super anal about everything and be tough to live with. Don't know much about Bird outside that she is a couple with Rapinoe and is not related to Larry Bird, unfortunately. Mayweather is a felon and Ronaldo is a likely sex offender. I'd have to hide out in the basement with Steph.
House 6: What a disaster this place would be. Embiid is a clown and would totally be the person that makes a mess but never helps clean up. Conor is somehow a worse version of Floyd. Neymar fulfills every vain celebrity stereotype. Taurasi and Nadal would probably be cool, but no way am I living with those other three.
