It's Ross' money...why do people care? If he turns out to last the entire season, we can be super bowl contenders for the first time in a long time. If not, oh well, Ross wasted money, but not draft picks.
If the Dolphins aren't bold, they won't make a playoff run. It looks like they know this, going after Manning, Flynn or RG3 is what it seems like they will do. They hopefully get one.
I'd rather have RG3, but that might not be possible. Manning plus someone like Tannehill maybe (and Matt Moore is still on the roster) would be better than an unknown in Flynn.
