An underfinanced team has as much chance as a snowball in Hades of winning any race on the Winston Cup Series tour.
There are so many variables to consider other than accidents, but if an underfinanced team were to win, a ten thousand to one shot at best, it would be at a restrictor plate track where there have been many "one-win-wonders".
But......... consider the team must practice no less than three times each week to perfect pit stops, and where do dedicated volunteers come from who are willing to do this religiously. How many engines can a team have when engines cost between 75 and 100,000 dollars each. And the engineers who help design the nuances necessary to eliminate aero push, etc., etc., etc..
No underfunded team can win. Any team running a FULL Winston Cup schedule and hanging in the top twenty-five in points is a well funded team. It has always been that way and it always will be that way. There are and have been many respectably financed teams who never finish in the top twenty, as demonstrated by Michael Waltrip when driving for Bahari Motor Sports or Bobby Hamilton with the Galaxy Motors team. Or yes, even Darrell Waltrip with his resume and financing from Western Auto as a sponsor failing to qualify and backpacker Carl Long taking the spot. Or Bill Elliott and his McDonalds team.
A solid commitment from EVERY team member must accompany each entrance the team makes through the garage gate and onto pit road. Every team member must eat, live, dream, sleep, work and poop NASCAR and winning to be in the top twenty-five. Underfunded !! By who's standards?? Any financial package less than eight million per year is underfunded by todays standards.
Of course guys like Dave Marcis, Jimmy Means and Brett Bodine could give lessons to underfunded teams on how to stay alive in the series. But even for them the price tag is and will eventually get too high.
