Are you guys joking? Crawdaunt is totally not NU. It's stats are about average for UU, and it has a pretty good movepool.
It would completely OWN anything in NU. It needs to be bumped up to UU. I use Crawdaunt regularly and can attest that it can anything in that NU tier.
EDIT: I also see Glalie, Wailord, and Whiscash down there. Those are much too strong for NU
