Very well. I watched a lot of USFL games. That league had many ideas the NFL ought to consider: chipped balls, 3pt PAT option, non-kick onside option (convert 4th & 12 from your own 25.) mic'd up refs, auto-review of all personal foul/roughing calls, 15yd PI, clock stoppage after 1st down inside 2 minutes (actually that's a college rule.) Clock NOT stopping after incomplete passes outside of 2 minutes remaining in the half.
