Ah right, but here are two thiongs:

1. he is too close to Kurama to make a throw effective 2. more important - Naruto wanted to use the technique to push Fox back, so clones can pull Kyuubi's chakra easier. In that case, it makes much more sense to make a thrust and keep contact with Rasenshuriken, that allows to apply additional force if necessary, that throw it and leave everything in technique's strength.
