I'll give him credit, since 2013, he's been running decent. Good for him, he deserves it. He's ran well. Unfortunately, well doesn't cut it in today's game. People look at Jr and think "Hey, we're at Daytona/Talladega. He might be in contention!" Shift focus to his teammates, Jimmie Johnson, and you see that he's almost always a threat to win every week. Everyone complains when he wins the Championship, but that goes to show how competitive he is, for 36 weeks out of the year.
Jr's had some great runs the past few year. I'm not a huge fan of him, probably mainly because of the mass cult-following he has, but in 2013, to see him win four races that year, that felt good. It's like the underdog finally breaking through. But unless he's having a day where he could win, he's running somewhere between tenth and fifteenth, and compaired to the other half of Hendrick (Elliott, Johnson. Sorry Kasey...), Penske, Gibbs, and SHR, that simply isn't going to cut it.
Great to see him running well, and having fun, but with the amount of talent out there, and arguably his own health, I don't see a Championship happening for Junebug.
