Buuuuuuut I'd run thr league almost concurrently with the NFL season...play on tuesday/wednesday or something...give guys a chance to jump to the NFL during the off-season and time to recover
Won’t work.
For one, it’ll be perceived as direct competition to the NFL and the new league won’t get any good time slots or a good deal with a network.
With the spring, they can get a great deal with a broadcast network because they have nothing for the weekend.
