Darrell Wallace Jr. needs to make more history in the NASCAR Camping World Truck Series before he advances to the sanctioning body's second-tier Nationwide Series.

So says precedent. So says Kyle Busch.

Granted, that declaration comes from someone hoping to assemble a sponsor package to field Wallace -- the first African-American to win a NASCAR touring series event in 63 years -- to race for his truck series team again next year. But Busch, a 124-time winner in NASCAR's top three series and the all-time leader with 62 Nationwide wins, has a point.

Wallace is talented. He has potential. His historic win at Martinsville Speedway created a wave of good will and perceived impetus for what may or may not stimulate a tepid sponsor market to fund his future endeavors.

But Wallace, ultimately, is 20, is 19 races into his first full truck season and has contested just four Nationwide races -- all in 2012 -- and needs steady work to develop enough to eventually follow fellow diversity program graduate Kyle Larson into Sprint Cup.

"I would have to say this certainly has to help some things," Busch said on Saturday after Wallace's win at Martinsville. "We've been trying for a month or so to try to continue to put things together for Darrell. I mean, I want to see him back in our trucks. I think a second season does a world of wonders.

"I think we've seen it with a lot of drivers over the years who have stayed one year in this and that and moved on, and then all of a sudden you don't see them anymore."

A teen prodigy who had to deal with age limitations and limited vacancies in front of him coming up with Roush Fenway Racing, Busch jumped with scant experience to Hendrick Motorsports for his full-season Nationwide debut in 2004. He succeeded. He is unusual.

"I think it takes a two‑year season to get your feet really wet and get dug in and get a platform and get comfortable in this sport, and the trucks is the best way to do that and the Nationwide is the best way to do that after that," Busch said. "There's a stepping stone here for a reason."

Wallace still has a relationship with Joe Gibbs Racing -- Busch is one of the team's Sprint Cup drivers -- with whom he has made all four Nationwide starts.
