Keselowski praises yet-to-be-announced 2016 rules package

Brad Keselowski is giving a big thumbs-up to NASCAR's yet-to-be-announced 2016 Sprint Cup Series rules package.

Keselowski, one of the drivers shaking down the new package at a test this week at Phoenix International Raceway, was asked on Twitter to offer his impressions so far.

It's pretty clear that the 2012 Sprint Cup Series champion and Team Penske driver likes what he feels and sees.

@keselowski @PhoenixRaceway @PJCoy What has NASCAR improved with the 2016 rules package, Brad?
