I agree with all of these.
I think 4154Z graduated, but 4154V looks like they’ll be really good, so I’m guessing you meant them. I’d they start any new teams, I imagine those might be good, too, based on how their middle school team did this year.
I’ve heard some members of LionTech X and Z are graduating, and the remaining members might combine into one team. Whatever they decide, I’m sure LionTech will continue to be a serious contender for all awards.
8471A (soon to be 5842 to match their FRC number) said they would be putting in a lot of effort this year, so I predict they will do well, too, especially since they’re making use of the forum (and the latter also applies to 7121B).
For Cyber Eagles, I know 77788H had one member graduate, and I think the rest still have at least one more year. 77788Z and most likely A and P still have several members who haven’t graduated, and likely 77788X, too (although if they only have 1-2 who stayed, those might join another team). 77788H was the best Florida team in TrueSkill who didn’t make it to Worlds this year (and maybe the best non-Worlds Florida teams overall).
Another serious contender would be 66333Z (one of the best North/Central Florida teams to miss Worlds), and maybe also 66333B.
4330 might be one to watch, too, especially if 4330M hasn’t graduated or 4330X’s remaining members are able to continue their success. The same for 50810E and 429A. Maybe also 550G based on their Worlds results, and/or other 550 teams who are still competing.
