I think this is my first post, but I just wanted to give my opinion on who I want to be in: (doing this on mobile, prepare for spelling mistakes)
Bill & Cathi - one of the strongest old teams in race history, the others being Meredith & Gretchen and Fran & Barry (at least who I remember), they will hopefully join the cast if they can still physically do it.
Jeremy & Sandy - not one of the most popular teams, but I personally like them. They only lost because their taxi driver took them to the wrong place (again, basing this on my memory), and they did get 2nd, which is hopefully good enough.
Joey 'Fitness' & Danny - an entertaining male team, lost because Rachel was faster than them (Rachel & Dave), and they could have gone really far. Bopper & Mark outshadow them though in my opinion.
Bopper & Mark - they are basically a more popular version of Joey & Danny, that's all I'll say.
Brendon & Rachel - do I have to say anything? They're either love or hate. I'm on the love side.
Amy & Daniel - they'd be my first pick for an Unfinished Business version of a returnee season. Taxi driver failed them, and they were likable, and I hated seeing them get eliminated.
Caitlin & Brittany - not likely, but they seemed like a good team especially since they originally got 6th in their last leg, ahead of all teams in the 2nd train.
Abbie & Ryan - they are probably my favorite team in season 21, with twinnies and chips tied tor 2nd. They are a competitive team, which I love. Frankfurt really screwed them over though.
Natalie & Nadiya - I love them, they have such a good energy and attitiude which I love, and they were a competent team.
Jaymes & James - they're fun people who are good racers, they almost always made me laugh a little in each episode.
Jessica & John - they can cause quite a bit of drama, which I hope makes for good TV. Please use your express pass if you get one.
Dave & Connor - inspirational racers who would've swept the race if they had working legs. I'd be surprised if they aren't in.
Pam & Winnie - decently strong racers who got screwed by a hidden ostrich in Brains. Entertaining, who accepted their loss easily.
Joey & Meghan - a team that is mostly hated, but I like them. They're young and filled with positive energy, which is what I like watching in the race. They rarely got negative, and they could have won legs if they didn't make little mistakes. They deserve a spot, but I honestly hate their fans. They are good, but not their Youtube fans.
Caroline & Jennifer - a female team that raced decently, and would be interesting to watch again, without the Hockey Bros.
Max & Katie - the likable not really villain team. Won 3 legs in a row, and had the most personality shown.
These racers are from 19-22, I don't wanna gove an opinion on TAR23 yet.
It exceeds the normal 11 teams I think, but I listed people who I want to see, not most likely to be in.
