I'd like to throw Team SCREAM, 4522 in the mix. They are a second year team that put a lot of us veterans to shame. They gave Bomb Squad a run for their money in Arkansas and put in a great performance in KC as well. Not to mention that they had a fully functioning robot completed in week 3 of build season.
Keep an eye out for 4522.
