We don’t need technology to see blatant offensive OL holding on many many plays. I’d like the league to make a statement outlining the complete parameters on a holding infraction. And make a commitment to consistently enforce them. There are way too many gray areas leading to wide variances on what is called and what is not called. I would be fine if the Rams were called for holding 5 times a game as long as it was clearly an infraction of the rules -and- the other team was called exactly the same.
The point is that broadcasting technology has forced other sports to be much, much more consistent in their calls.
Baseball is having a bit of a renaissance and that in no small part can be credited to Fox putting up that "Strike Zone". The Umpires HATED it and I think they even threatened a strike, but MLB wasn't gonna give up the network money and baseball is actually a sport, so...
You just don't see those strike zones moved 6 inches, typically, and when an Ump is grossly miscalling games, the entire baseball world sees it and the players don't have to say anything. For the most part, tho, strikes are strikes and balls are balls.
The point is that younger fans have never known a time when life was analog, so they have very little tolerance for the "it removes the human element" argument when that argument is only trotted out to justify the refs missing calls.
The NFL will drag their feet, but as the networks continue to implement more tech and data and data analysis tools, the NFL will have to adjust or simply allow the networks to further expose where the line is between true competition and when the NFL seeks to "adjust/further the narrative".
