I love the skills challenge, they should expand it. The best part of All-star weekend is the slam dunk and 3-point contests, and the best part of the Midsummer Classic is the Home Run Derby.
I want more of that stuff. 1st and 20 at the 30 simulations with both offenses going against both defenses, kind of like the penalty kick things at the end of european soccer games. Or like overtime in college games. Who's better at stopping this/scoring with this?
Hands challenges like the WR thing at the combine: run through a gauntlet of 5 QBs on each side firing passes just 2 seconds between each one.
Coffin corner punting challenge, 60 yard field goals from all the way on the out of bounds line, who can hook it? QB challenges where you need to hit a WR with 2 corners on him, or be more accurate than a computer-aligned jugs machine.
That stuff would be sweet, like the strongman competition stuff. Vote on the events every year, so it changes. Like next year fans want to see a footrace between all the RBs, DBs, and WRs. We don't need to see it every year, replace it with Olineman vs Dlineman tug of war the next year.
