I get the OPs point, and if it were me, I might be open to being that petty. Because in a way, it's not petty at all. I'd be pissed if I were Tua. A blue-chip QB prospect coming out of the top NCAA program recovering from a brutal career-ending hip injury and you're selected 5th only to have your legs chopped out underneath you every step of the way, by the one person/organization that should always have your back.
Yeah, if I were Tua, I'd say f*ck the Dolphins, too. The good thing is I think Tua is likely a much better Christian than me, more mature than me, and also recognizes that Ross ain't likely to be around much longer anyways. If he balls out this year, and the Dolphins offer him a big contract, and he gets to live in Miami and be a starting QB with no state-income tax, I suspect he's going to sign on the dotted line.
