The Miami Dolphins rebuilt their team in 2019. It didn't work. They tried again in 2022, but that hasn't worked either. One of the reasons is continuity, but you can't have that with so much turnover.
Fans know that you can't pay everyone in the NFL a big, long contract. You have to supplement the roster with players that are on short-term deals, but too many of those types of contracts eventually bite you.
For Chris Grier and the Dolphins, those deals are biting, and when you can't hit on players in the draft, it puts a lot of pressure on the guys making all the money.
