Depends on how you define entertaining really.
I resigned myself to us tanking as soon as Coach Flo signed that extra-long contract and Grier started talking about the rebuild. Many people continued to hold out hope that it would be more of a "reload" or even "rebuild" … and if they still think that they're probably quite unhappy today. But, if you define entertaining as watching young players get an opportunity to blossom, and you see the individual development of the players and the units, it can still be entertaining. If you're dead-set on making the playoffs … well I think those people are going to be disappointed … just no other way to say it.
Personally, I'm hoping we build a team that can compete post-Belichick, so I'm OK with tanking. I'm tired of mediocrity and trying to patch a bad wall with extra-thick spackle and a new paint job. I want to tear it down to the foundation and build a great new house, and I'm OK with living through the construction it will take.
I miss Don Shula and winning all the time. I miss dominating players like Dan Marino and Larry Csonka. I want to dream of winning Super Bowls, not just of making the playoffs. I miss the Dolphins being great, and I'm OK with sucking for a year or two if we can finally return to greatness. I'm hoping we can. So me … I'm going to find our tanking/rebuilding 2019 team entertaining, but that's more of a decision than an observation.
