For north champs, I think 503 has a strong chance (assuming they win this weekend…if not, it’s open).
For south champs, I have to think 3132 has a really good shot – their video this year is easily the best I’ve seen since 27’s, and how many other teams can claim that they’ve started FIRST on a continent? 1311 is a bit of a dark horse with an amazing program, and I think a lot of people underestimate 1540 (though of course I’m a bit biased). 1902 also has an solid program.
(The one caveat I see to 3132 is that they’re still significantly younger than pretty much every other elite Chairman’s team. 1538 to my knowledge holds the record for youngest team to win Chairman’s in the modern era – 9 years old – and 3132 is 8 years old. Most of the elite teams are at least ten years old, many quite a bit older, but 3132 has packed a lot into their 8 years, to their credit.)
A few broader thoughts…I think that you probably need a minimum of 4 RCAs to be competitive at the CCA level these days (might even be 5 or 6). Additionally, I think there’s a bit of an imbalance between the two championships in terms of Chairman’s competitiveness, so I’m wondering if in future years we’ll start to see elite (top 5) Chairman’s teams picking which championship to attend based on other Chairman’s teams there. Particularly if 503 wins in St. Louis this year, north champs will be significantly less competitive than south champs moving forward, so a weird little meta-game could emerge there as the top programs pick which event to attend.
