I think such a list is simple to construct. First, any list without 67 and 71 is dumb (based on World Championships alone). Next, 1114 and 2056 have been elite more consistently in the last 9 years than any other teams in FRC history have been in that long a stretch of time. To me, those four teams are entirely unquestionable. The last spot is a bit harder. If you're biased towards early FRC history, you go with 47. If you're not interested in the 90s, you go with 254 or 987, or another team of that caliber.
