The original XFL had some different rules around certain types of hits, and it also emphasized the players' personas more by letting them choose the names on their jerseys, trash talk, take their helmet off for celebrations, etc. It was and is still run by the same people behind WWE.

Now I take it they're moving in a different direction. Is there generally more or less concern for player safety in the XFL now, compared to the NFL?

WWE = Fake Wrestling as Entertainment. Lots of drama, lots of chugging beers, throwing people tables, etc. I'm known to watch a Smackdown once in awhile for a good laugh.
