Busch is the 16th driver in NASCAR history to win multiple championships, and one of only five to win titles in both the Cup Series and the second-tier Xfinity Series.
That was evident this week in JGR's precedent-setting three entries in the championship race.
Denny Hamlin's championship run was foiled by the tale of the tape.
NASCAR moved "championship weekend" to Phoenix in 2020, leaving Homestead to settle for a March race date amid Spring Crack.
Hamlin fell out of contention when a crew member placed a large piece of tape across the front of his vehicle, causing his engine to overheat leading to an unscheduled pit stop.
Harvick saw an opening after Truex and Busch respectively made pit stops on Laps 209 and 210. J.D. hired a young Hamlin and gave him his first opportunity in NASCAR's big leagues. Our best chance was to have a caution there at the end, and we never got one. "But with the overheating, I could not". I was going to blow up.
"Did I make it exciting adequate?" Try out for a caution. "Try for a miracle".
Hamlin's emotional win at Daytona was, Joe Gibbs believes, highly motivational to the entire team.
Busch gave Gibbs his fifth Cup title and bookended a season in which the Gibbs cars opened the year 1-2-3 at the Daytona 500.
Kevin Harvick took a gamble by holding off on his final pit stop Sunday.
With Michael Jordan rooting him on from the track, Hamlin finished 10th and had the worst finish of the four championship drivers.
Homestead-Miami Speedway announced Friday that all seats in the grandstands have been sold for the EcoBoost 400, although many tickets can be found in secondary markets well below face value.
Joe Gibbs Racing drivers, Martin Truex Jr., Kyle Busch and Denny Hamlin will compete against Stewart-Haas Racing driver Kevin Harvick for the series championship on Sunday afternoon. Hamlin smiled a little bit bit and nodded as he listened to Gabehart's phrases. But nothing could console either man over a season that collapsed in the pits over a small mistake. "We were just trying to pull off a really hard play and didn't get it done. Unfortunately, as very good as our automobile was at the finish, I really don't know if it desired it anyway".
The NASCAR Cup Series championship will be decided at Homestead-Miami Speedway. We were hot early in 2015 when Kyle came back.
J.D. Gibbs died January 11 at age 49 after a lengthy fight against a degenerative neurological disease. I don't feel I could have done a better job. Hamlin gathered his oldest and closest friends around him for a picture at the 11 vehicle and they shouted out the (hashtag) LFG catchphrase he's been using in his social media posts. But Hamlin's auto seemed to come to life as the sun set over the 1.5-mile speedway.
He worked his way back toward the front but had trouble weaving past Joey Logano and Erik Jones at the start of the third stage. "And I've said it a million times, if I didn't work for him, I wouldn't be where I am now".
Hamlin turns 39 on Monday and organized a large bash for quickly after the race. It's more a birthday party now than a championship celebration.
It was a lesson learned from his first Cup title in 2015 when Busch ruined the massive championship banner doing smoke-filled burnouts. This race has come down to that every year.
Truex's crew mixed up the right- and left-side front tires on lap 120, causing steering issues and forcing the 2017 series champion back to pit road. Truex clearly had the dominant vehicle early in the title bout. "Sometimes we may not be the best, sometimes we may not have the right track position. It's going to be okay, and we're going to be strong, and I guarantee you it's going to motivate Chris (Gabehart, crew chief) even more than what he already is".
"I've got a lot on my plate", he said.
