Well, maybe. Zeke was given a $25m fully guaranteed contract before he ever took a handoff in an NFL game. He could have been an NFL dud and the team would still be out all that money (which may end up being the case with Fournette who was given $27m fully guaranteed, and definitely was the case with Trent Richardson who got $20m fully guaranteed). And if they play out the 5th year option, he gets another $9m, taking him to $34m total. Tag him in 2021, that's another $13.5m (estimate). Nearly $48m total in NFL money, not counting endorsements ain't bad - and that's Zeke's "worst case" from your above example.The running backs are correct in that they are severely underpaid during those first 5-6 years.
Are you suggesting that the guys who aren't worth their contract should keep all that money, and guys who do a bit better than those large contracts should all hold out for more? That would be a no win proposition for the teams. Either draft a crap player, or if you actually hit on the guy you have to redo the deal and pay him huge money, which you above said isn't a smart move. What that will cause is no team will use a first or second round pick on a RB again.
