First, cut schedule to 16 games, ending on Day 6 a.m. cycle, and move up reg. season start 24 hours. ST is long enough without the lay day and a half, almost two for the pm2 starts.
Then, to get owners really involved, have 24-hour lightning round free agency bidding, beginning on the pm cycle and ending on the next day's pm cycle. You could have five of them (Day 1 to Day 2, 2 to 3, 3 to 4, 4 to 5, 5 to 6.) They could be a mix of Internationals ... undrafted U.S. players ... even leftover A/B free agents. Have one or two appear each pm cycle, with bidding ending 24 hours later, announcement a half-cycle later. The leftover ML free agents would announce they'd chosen a new agent, Monty Hall, and they're ready to Let's Make a Deal! They drop their demands down to a starting point of - whatever - $1 million.
Of course, the players would have to be worth bidding on.. nothing of this DITR stuff. Might also take the sting out of lousy draft and Intl pools to come.
