I believe that Scott has what it takes to make it big in Motorsports. When I look at Scott I see the next Jimmie Johnson, he really is a sponsor’s dream. He really impresses me to see him do such a great job behind the wheel,” Patterson stated. On December 11–12, 2007 Stenzel attended Finish Line Racing School headed up by Mike Loescher.

Jeff Spraker, and his skilled crew, have taken me and this Wood Brothers Ford Fusion on at the last minute. Everything is coming together smoothly with everyone pulling extra duty. Plus, as a team we’ve been able to gel. Spraker’s been to Daytona several times. He knows what it takes to lead and finish up front, but he’s yet to win one. Now, we share the same goal – to win at Daytona.” On April 23, 2010, Spraker agreed to field the car for Stenzel. Stenzel qualified 28th at Talladega Superspeedway. After 250 miles were completed in the race, he finished in the 7th-place position. He received the CGS Hard Charger award for passing the most cars during the race.
