The Chicago Bulls fell to the Memphis Grizzlies 100-104 on Friday night, dropping their second preseason game in a matchup that gave fans plenty to talk about.

There was some good, some bad and some downright ugly basketball from Chicago. The Bulls looked lost at times in the first half before coming out of the locker room looking like a completely different team.

Some young players are starting to make their mark, but a few familiar problems are already rearing their ugly heads.

Here's the good, the bad and the ugly from Friday night's loss.

Dailyn Swain is starting to figure this point guard thing out.

Swain looked like a completely different player against Memphis than he did against Phoenix. After looking hesitant and uncomfortable handling the ball in Chicago's preseason opener, Swain was much more confident bringing the ball up the floor and initiating the offense. He made some beautiful passes, got into the paint and showed flashes of the offensive creativity that made him such an intriguing prospect coming out of Texas.

Swain also looked comfortable without the ball, making some excellent cuts and finishing a couple of impressive dunks. Add in two steals on the defensive end and you've got yourself a pretty encouraging night for the rookie.

Nobody's expecting Swain to become a starting-caliber point guard overnight, but this was a big step in the right direction.

Whatever Tiago Splitter said at halftime, he needs to say it more often. The Bulls came out of halftime looking like somebody had lit a fire underneath them. The energy was completely different, the offense was moving and Chicago finally looked like it wanted to be there.

Yes, Memphis sat its starters in the second half. Who cares?

Good teams need to be able to flip a switch coming out of halftime, timeouts and quarter breaks. The Bulls have struggled with that for years, so seeing some actual halftime adjustments was refreshing.

Caleb Wilson certainly appreciated the change.

After a quiet first half, Wilson became a focal point of Chicago's offense in the third quarter and finished with 21 points. The Bulls need to make getting Wilson involved early a priority. He's too talented to spend entire stretches standing around waiting for somebody to find him.

Leonard Miller is making it awfully hard to keep him on the bench.

Two preseason games in and Miller is already making a serious case for rotational minutes. The hustle is there, the basketball IQ is impressive and his jumper looks increasingly comfortable. Miller finished Friday's game with 12 points and 11 rebounds for a double-double off the bench, doing a little bit of everything for Chicago.

There's plenty of competition for minutes at forward, but if Miller keeps playing like this, Splitter is going to have a difficult time justifying leaving him out of the rotation.

Tobe Awaka is fighting for his life out there.

Awaka deserves a ton of credit for battling on the interior, but there's only so much a guy his size can do against legitimate seven-footers. Zach Edey and Cam Boozer gave Chicago fits around the basket, and the absence of Nic Claxton, Jalen Smith and Zach Collins was painfully obvious. Awaka is a tremendous rebounder and brings great energy, but expecting him to consistently battle players who tower over him is asking a little too much.

Chicago needs its big men back, and preferably sooner rather than later.

Somebody needs to teach these forwards how to set a screen.

Splitter has brought some interesting new wrinkles to Chicago's halfcourt offense. There's more off-ball movement, more screening actions and a lot less standing around watching somebody dribble. It's been refreshing to watch, but there's just one problem.

The screens aren't actually hitting anybody.

Chicago's forwards have a habit of slipping screens before making meaningful contact, allowing defenders to navigate through the action without much resistance.

You can draw up the prettiest offensive sets in the world, but if your screens aren't creating separation, what's the point?

It's a small detail that could make a massive difference in how effective this new offense becomes.

The Bulls' perimeter defense is looking like a disaster waiting to happen.

Splitter wants to build a defense capable of switching across all five positions.

Sounds great, right?

The Bulls finally have legitimate positional size throughout much of their roster. They've got long, athletic forwards and guards who should theoretically be able to switch onto multiple positions. Unfortunately, there's a pretty big difference between looking like a good defensive team and actually being one.

Josh Giddey continues to struggle navigating switches in the screen game, while Caleb Wilson and Matas Buzelis have been taking some downright awful angles on their closeouts. Opposing players are blowing right past Chicago's initial defenders, forcing everyone else to scramble around trying to put out fires. One bad closeout turns into a defensive rotation. That rotation turns into an open shooter or an easy look at the rim.

It's a domino effect, and right now the Bulls are knocking over the first domino themselves.

The frustrating part is that the physical tools are there. Chicago has the length and athleticism to be a respectable defensive team, but those advantages mean absolutely nothing without discipline and execution. Switching everything isn't some magical solution to defensive problems. If anything, it makes communication and individual accountability even more important.

And right now, the Bulls aren't showing nearly enough of either.

It's only preseason, so there's no reason to hit the panic button just yet. But if Chicago wants to be anything more than another exciting offensive team that can't stop anybody, Splitter has some serious work to do.

The offense is showing promise, the young guys are making strides and there's plenty to be excited about, but somebody has to play defense eventually.

Chicago continues their preseason action in Denver against the Nuggets on Sunday night and will have another opportunity to show a defensive improvement.
