NFL and the XFL will join


The NFL and XFL have reached a partnership agreement according to the Tweet from Dany Garcia, the Chairwoman of the XFL.  Dwayne "The Rock" Johnson tweeted out confirmation that such great message is awesome and that joining forces will advance and grow the game of football.  The breakdown of their collaboration follows:

-XFL will act as a league for the NFL to experiment with new rules.

-Officials will use the XFL to develop their skills.

-Various playing surfaces and equipment will also be tested.

During the XFL 2.0, rules were improved from the original XFL and current NFL with gameplay innovations, timing changes, and the common sense rules.  Will all the improvements remain as is or will the league default to NFL standards?  These are the questions that need to be answered for full understanding.
