Let's be honest, the Carolina Panthers hardly resemble anything that an NFL team should look like. In most sports leagues in other parts of the world like Europe or even in the American Football league in Japan (X-League), they'd be prime candidates for relegation so far. But, how would such a relegation and promotion system work? Well, here is an idea that I have thought of.
I am aware the NFL likes to have a few football leagues in the summer. I think this is where the CFL and a lot of the indoor leagues come in. As for the UFL, which has produced legitimate talent, I think their season should be moved to during the season. Their regular season games should be played on Tuesday evenings, Wednesday evenings, and Friday evenings. This keeps them out of the way of NFL games and allows for daily football games between the NFL, UFL, and college football. Their championship could be the Sunday between the conference championships and the Super Bowl (and move the Pro bowl back to after the SB). To add to the UFL Championship stakes, the winner of the UFL Bowl would earn promotion to the NFL. The worst team in the NFL would be relegated to the UFL.
Then, for the draft, the NFL would have their draft first. Then, about a week or two later, THE UFL would have their draft. The champion of the UFL who got promoted to the NFL would have the number 1 pick, while the relegated team has the last pick in the UFL pick. This, to add excitement, it would be possible for a team to be newly promoted, like say the Birmingham Stallions who would be an exciting addition to the NFC South, to be newly promoted and win the Super Bowl.
This would probably hurt a team like the Panthers, but they hurt our eyes from having to watch them suck routinely. The NFL is supposed to have the best quality football teams. So, why not relegate the worst team yearly to the UFL like they do in other parts of the world?
