67. Their record proves it. In a game where 50% of the top robots do the exact same thing, its takes more than just robot design to win it all. 67 obviously had something else, since any number of other robots could do just what they do, as fast or even faster. 67 dedication to strategy throughout the match is I believe why they have the most wins of any single FRC season, ever (district system may have helped a bit
)
Seriously though, watch some of their matches on youtube. They always score 15+ balls, and typically deliver one or two empty cells on top of that. I can think of at least 20 robots capable of doing exactly what 67 did if they had HOT's drivers. This year's game made it painfully clear that driver's can make or break a season.
