I don't love it, I think it's still too favorable to the team getting the ball second who will know what they need to get and play with the mindset that will go for it on any 4th downs.
I still think that the previous OT scoring rules (first team to possess scoring a TD ends the game, FG gives the other team a possession) were the best that we've had and the most balanced in terms of win % between the team receiving the ball first or second. I remember seeing that it was almost a 50%/50% split in terms of who won the game between the team getting the ball first or second under those rules. The biggest flaw from this format in my opinion was not the scoring/possession rules themselves, but rather the luck factor of the coin flip arbitrarily awarding the first possession.
I believe that the best solution to the NFL's overtime rules would be to go back the previous scoring and possession format, but remove the coin flip at the beginning of OT to determine who gets the ball first. Instead, the beginning of overtime can simply be a continuation of the end of the 4th quarter; so the team with the ball last when the clock hits 0:00 in the 4th has the ball with the same field position and in the same situation to start overtime. This would make strategy and game management decisions in the 4th quarter even more paramount as some of those decisions can directly impact the first possession of overtime in the event of a tie game at the end of regulation.
For example, a team down 7 pts scoring a TD late in the 4th quarter would have a more interesting decision to make for the convert: go for 2 to decide the game right then and there, or go for 1 to tie the game, but knowing that you would then be kicking off and playing defense to start OT where a walk-off TD on the first possession can end the game. Similarly a team down 3 running a two minute drill would have more incentive to drive for a winning TD in regulation, if they're too conservative or lack execution and have to settle for a field goal to tie, they would start OT on defense.
I've gone through multiple scenarios under this idea and haven't been able to think of one yet where this would be worse than the old scoring/possession format with the coin toss. I also think the general fan sentiment would be much more accepting of a team not getting an overtime possession in games featuring a first possesion walk-off TD if the luck factor from the coin toss was completely removed from deciding which team gets the ball first.
It would add an extra layer to coaching strategy in the 4th quarter. We would be able to go over and analyze all of the game management decisions of the teams and coaches that led to the overtime unfolding in the way that it did. The reason a team would not get a chance with the ball in overtime would be more closely tied to that team's coaching decisions and execution, especially late in games, which is much easier to stomach as a fan than a 50/50 coin flip.
