Ya, people who don't at least root for Jay while he is in there really can't be a fan. You might not want him there, and curse on him all the time, but if you don't root for ALL 11 men on the field, why do you like the Dolphins?
He isn't going anywhere for now, so you might as well root for him until we bring in an adequate replacement that you will be happy with.
Would I love a bonafide pro-bowl QB here? Damn right. Do we have one now? No. But I'll be damned if I don't cheer Jay on every second of every game. I am a Phin fan, I root for who is on the field during the games, and worry about complaining after the games.
