I disagree that there's any kind of good chance that Grant "does something" there. Granted, Miami was almost certainly going to lose no matter what thanks to the spendthrift use of time-outs during the Seattle drive. But that's neither here nor there. The most likely outcome of Grant's play is that Miami ends up with worse field position and less time on the clock.
If Miami is in that situation, but up by 2 and kicking off, I'd love it if the other team tried running it out-- unless the guy running it out was Devin Hester, Gayle Sayers, Deion Sanders, etc.
