Growing up in California, I was lucky in a way... since there were very few Dolphins fans, there were very few opportunities to encounter the stupid bar fan type.
Heh! So I always accociated the dumb jock stuff with Raiders fans.
I think in general, NFL fans are more afraid of busting out on a quarterback than they are of passing up a franchise quarterback and letting somebody else have him. Which is the wrong perspective in my opinion. They just don't want their team to get laughed at. The Dolphins have been laughed at for decades.
Fans believe that busting on a quarterback high sets your organization back a decade - because that's the way it used to be - but it's not that way anymore. Back before the rookie salary cap, you had to make a much more significant financial commitment to the quarterback. It used to be your high QB draft pick had to sit for a year or two behind a veteran, learn the ropes - then you needed at minimum 30 starts to get an evaluation of him according to the old Bill Parcells rules....
If it didn't work out, then you had to draft another one high and repeat the process. Yeah, maybe a decade has passed by the time all this has taken place.
However, it's just not the case anymore. You take a QB high, they play immediately now because quarterbacks are so much more developed coming out of high school now and entering college than they used to be. The financial commitment isn't as significant. You don't need 30 starts anymore to see what you have. The entire process is expedited now. You're not going to set your organization back a decade even if you miss. Busting out on a quarterback isn't the end of the world.
As Awsi has pointed out many times, the worse case scenario isn't busting out on a quarterback. The worst case scenario is what Miami went through with Ryan Tannehill. Drafting a mediocre quarterback high that puts you in QB purgatory, and forces you to make a financial commitment to the mediocrity on his 2nd contract, or cut bait and start over again. Most front offices aren't going to be given the latter option and need to make the only decision they can to remain employed.
The best way to build a team that can compete is to get a young QB in your building that can play on a rookie contract and build around him.
