The North Carolina Tar Heels lost at home again on Saturday night to the Louisville Cardinals, 16-14.

It was an impressive defensive effort from the Tar Heels against an explosive Cardinals offense. Unfortunately, UNC's offense couldn't produce consistent scoring drives, leaving potential points on the field far too often.

The game sadly ended in an unfortunate and unnecessary fight that may cost a few players from the Tar Heels their ability to play next week. Otherwise, here are some of the biggest takeaways from Saturday night's loss at Kenan Stadium.

Cardinals Keep UNC From Bowling Another Week

We'll have to wait another week, at least, until the Tar Heels secure their sixth win of the season.

Once again, North Carolina came close at the end to secure a huge win, a program-defining moment under Bill Belichick's tenure, but constant offensive mistakes, the lack of scoring drives, and costly penalties prevented UNC from taking an important next step for another week.

Complementary Football Remains a Big Issue

The Tar Heels continue to struggle to play consistent, complementary football, which has led to many of the losses or close victories that they've had this season. At no point do you see North Carolina put together consecutive offensive and defensive drives that result in stops and touchdowns at an efficient level.

This is just one of the several key issues for a Tar Heels team that has shown growth this season, but they are nowhere close to where they want to be. Coaches and players have to take accountability in this one.

Travis Burgess Makes His Debut

On the Tar Heels' first drive of the second half, Billy Edwards Jr. was crushed on a blitz and stayed down for a while. He didn't return to the game, handing the keys to the offense to freshman quarterback Travis Burgess, who made some impressive throws in the second half to keep North Carolina alive while adding a new element to the offense with his athleticism and impressive arm talent.

I wrote earlier in the week that North Carolina should consider looking at Burgess or Miles O'Neill during games, but not in this fashion— you never want it to happen this way. Even so, the former blue-chip recruit flashed before our eyes, and there should be some serious talk about Burgess splitting snaps or outright starting if Edwards can't go against Virginia.

Tar Heels Defense Stays Tough

North Carolina's defense had an impressive night against Louisville's explosive offense. Unfortunately, the offense couldn't respond enough to give it the flowers it deserved.

This goes back to complementary football, which the defense was unable to get at multiple points tonight. UNC played tough and physical against one of the best offenses in the country, and that should be a massive standout from tonight's game, but instead of reveling in victory, they will only cherish it in passing because of the defeat.
