Harvick got to the bottom. He even pulled back up onto the track when the caution came out.
I watched more football than I did with this race. Congrats to Jeff, but everyone was essentially playing "puck protect" mode. I fault ESPN for overhyping the race because I was expecting some desperate teams to go off-strategy or do something they normally wouldn't do in any other circumstance, but they were too conservative.
The way I see it the race had long green runs that kept people from trying the off-strategy stuff. If there was a late race caution, we probably would have seen several different pit strategies.
