This issue isn't the NFL's fault. It's the Bengals trying to get away with one here. Nothing the NFL can do in this situation. The arbitrator will make the determination. We may see another grievance filed by Teddy Bridgewater against the Vikings for similar reasons.
Well, it's clear the CBA needs a significant overhaul.
Among the things that need to be fixed:
Franchise Tag: It's too much in favor of owners. One tag, one time. That should be enough for teams to figure things out.
No Salary Cap: It's ridiculous that ANY player in a sport with a roster of 53 can take upwards of 20% of the cap. I didn't use to like it, but the NBA model is at least a place to start. I wouldn't want to use it as is, but it would alleviate many of the Franchise issues. I realize the NFLPA won't like it, but it will benefit the sport in the long run AND it will get more guys paid. It won't change the average, but it will improve the mean. THAT'S what a union should be doing for its members, looking out for all members, not just the highest earners.
Rookie scale: Well, they took that pendulum and mad swung it from Bradford to first rounders getting very little and having to wait as many as 7 years before getting to that guaranteed money of the second contract. They need to shorten rookie deals a year on the top end. Four years max with 1 franchise year.
Marijuana: It needs to not be a bad thing anymore. Moreover, the NFL needs to start advocating for CBD research and funding it since it may be the thing that saves football. You know those moms who won't let their kid play football for fear of neuro injury? Well a LOT of those same moms are giving their beloved pets CBD oil and mitigating a LOT of issues.
Discipline: The inconsistencies have made this a disaster. If we can't rely on the judgment of a corporate lawyer (who knew?), then it's time for the league and NFLPA to agree on discipline with respect to fighting, PED use (and beyond MJ, there should be a much more clear issue with actual PEDs and drug use with respect to suspensions. I have much less issue with Josh Gordon's MJ use than someone who's taken actual performing enhancing drugs) and domestic violence. This ongoing Zeke Elliott mess is a pox on everyone's house. It puts the NFLPA in position to want little/no punishment for someone who committed violence and it puts the NFL in position to prosecute players based on arbitrary standards.
Offseason: Teams took way too much advantage of the off-season so that players never really had any time off because "voluntary" wasn't really voluntary. Once again, the answer was to swing the pendulum from too much to too little. The league and the NFLPA have to come to some agreement to allow for player contact with coaches/ownership in a way where players don't feel that it's mandatory. At the very least, new coaches should get extra access to players for no other reason than it will improve the product the NFL and its players present to fans.
Officiating: We need full-time refs. Why? Well, because full-time refs can spend their full time working at a league facility going over rule changes and finding a UNIFORM way to call not only the rules at large, but especially the Points of Interest that seem to be the NFL's version of the Strike Zone. The biggest issue isn't too many calls, although that can be less than fun. The biggest problem is that officiating is a factor in who wins because so many calls are on the margin. We all know for instance that offensive holding happens on nearly every play and for the sake of the game they aren't going to call it every play. So, with that, how is the LEAGUE going to call it. Teams shouldn't have to play the first quarter to see how a game is going to be officiated. That's especially true for Offensive Holding and Pass Interference...and what is a damned catch. Uniformity will allow teams to better understand not only the rules, but how they will be enforced actually during play. Moreover, full-time refs would be able to work with each team so that they understand. There should never be a time where a guy on one team gets called for every infraction (GRob), but another doesn't (whichever OL Quinn is facing). That uniformity will lessen the demand to have calls reviewed by "big officiating brother" in NY and ultimately increase the pace of play.
It's just a start, but both sides have to put the product first. That means both sides can win if they work together.
