A team who deserves a mention who isn't on this list is 47/51.
For those of you who weren't around in the late 90's, early 2000's, it's very difficult to understand just how good Team 47 was back then.
1996 - Champs Rookie All-Star
1997 - Champs Finalist
1998 - Three regional wins, then got double teamed by the opponents in a 1 v 1 v 1 elimination match, thus helping lead to the removal of the old 1 v 1 v 1 format
2000 - A robot which many FIRSTers consider the best of all time, only to experience a catastrophic broken weld on their arm during the elimination rounds.
During this time period "Chief" was on a completely different level than most of FIRST. I remember thinking that it was just a matter of time until they won a Championship. So their run of success as of late doesn't compare to teams like 233 and 2056, but for their past successes they need to be part of this discussion.
Here's a post I made back in 2003 about a very similar discussion to this one. Kind of ironic looking back at it.
