HOMESTEAD, Fla. -- NASCAR will issue the requisite warning to drivers Sunday morning: Let the race play out naturally.In this scenario, naturally could mean crazily.Before this third version of the elimination-style Chase for the Sprint Cup, look at how the first two versions were decided at Homestead-Miami Speedway -- the site of the seasons final race -- with a race within the race, as the top finisher among the four finalists earns the title.* More crazy: In 2014, a Blake Koch-J.J. Yeley wreck with 12 laps remaining set up a dash for the finish, ruining the hopes of leader Denny Hamlin, who opted to stay out and became a sitting duck on the ensuing restart. Kevin Harvick went from 12th to the win, thanks to fresh tires and a strong car.* More natural: In 2015, a caution for debris with nine laps remaining bunched the field up, but Kyle Busch, the leader of the Chase drivers at the time, remained in front of his competitors on pit road. Busch was side-by-side with nemesis Brad Keselowski on the final restart, and Keselowski gave Busch -- and then Harvick behind him -- plenty of room to duke it out for the title. Busch was the eventual champion.The four 2016 finalists -- Kyle Busch (starting ninth), Carl Edwards (10th), Joey Logano (13th) and Jimmie Johnson (14th) -- have played nice with each other so far.Will the gloves come off? Or will it be one ecstatic driver with three disappointed but understanding drivers after the race? Will Michael McDowell (or someone else) have a tire issue in the waning laps -- as he has done in two of the past nine races -- and affect the outcome?Oh, and theres that matter of Johnson attempting to tie Richard Petty and Dale Earnhardt with seven Cup titles.Im not running from it, Johnson said. Im not hiding from it. Its just truthfully right now for me to do my job and the preparation and all the stuff that goes into racing and being competitive. Its just not top of mind.?What to watch for:Team spirit: For the first time in the elimination format, two drivers from the same organization are among the four finalists.Busch and Edwards have joked around with each other this week, but they obviously cant forget what happened at Richmond earlier this year, when Edwards moved Busch for the win.Both drivers have made aggressive moves in the past, some that have worked and others that have ended up as futile. Team owner Joe Gibbs might not want them to wreck each other, but they both are so competitive that it would be hard to see them race without a little bit of aggression and nastiness with a championship on the line. Busch would love to prove people wrong and win back-to-back championships in a format that doesnt favor such a feat; Edwards wants to win a Cup title after three near misses in his career.Im not nervous or anything, Gibbs said Friday. I just walked into the womens restroom. Other than that, no harm, no foul.Rebounds from qualifying: None of the finalists seemed all that thrilled with their qualifying.We all sucked, Logano said.To be honest, qualifying in the top 15 isnt wonderful.But it wasnt horrible.We shoot for No.?1, Logano said. Thats what we shoot for. We all want to be faster than that, Im sure. Im sure not just [my] team, everyone wants to be quicker than that when you come here.But the good side is that were all around each other, so the penalty of starting back there isnt too severe, because everyone is in the same boat.None of the four drivers have problematic pit stalls from qualifying, and Edwards and Busch have openings on their way in, so they know they will have clear
