I'm a pessimist with the Dolphins. Although in my defense, I moved here in 1999 for the second time (the first time I only lived here for two years in the early 90s) and the only difference between us, and junk teams like the Bengals and Browns in that 1999 to present time-frame is number of arrests and staph infections. I don't know what it's like for this team to have a franchise quarterback. I only saw Marino one year and that was the year we got 62-7'd.
With the Heat I'm an optimist because in that same time-frame they've built three different contending eras.
