The fact that Sprint Cup races are so long makes them endurance races also.
I realise you are talking about a Nationwide series race but in general NASCAR races are about putting yourself in position to win the race and to finish first you must first finish.
To race to the front each and every lap will use up your tires early on in a run with nothing left for later in that same run.
These races are long enough to pick your way through to the front so no need to punt your way there.
I believe each racer would lead every lap if they could except during the restrictor plate races where some decide to run in the back of the pack (to avoid the big one) and with limited laps left in the race head towards the front.
Edwards did that, was battling for the win, crashed and did not finish the race. Good strategy untill the crash.
Sometimes strategy alone can win a race and sometimes the best strategy gets foiled by any number of circumstances.
To win an NASCAR race you need good equipment, a good pit crew and just as important (if not more) is luck. Good luck on your part and bad luck for your opponents.
One dropped lug nut during a pit stop can certainly cost you a win.
In Busch's case a flat tire.
I don't see these races played out quite the way you do Metar but I do enjoy them very much. I have watched them now for many years and I think it's great every race, the whole race. Attending them is even better.
On a similar note, it was good to watch Skinner get out of his truck after such a crash last night with no injures. Wow.
If anyone wants to watch a series that races for the win every lap then watch that series, those guys are nuts.
