NASHVILLE – The Titans are 2-2 after four games this season, with wins over the Chargers and Bengals, and losses to the Saints and Browns.
Here's a look at four things I know after four games, and four things I still don't know:
FOUR THINGS I KNOW:
1. The Titans Have a Kicker.
Veteran Nick Folk has been money since joining the team in late August.
Folk is a perfect 10-of-10 on his field goal attempts, and 6-of-6 on PATs.
Folk made his 65th consecutive field goal on attempts from less than 40 yards on Sunday, when he also made a 53-yard kick.
Folk has made 18 consecutive field goals dating back to last season, which is the NFL's longest active streak.
2. Derrick Henry's Still Got It.
If you don't believe it, put in the tape from Sunday's game.
Henry steamrolled his way to 122 rushing yards against the Bengals, and he punished some tacklers in the process. Henry avoided plenty of others, of course, en route to racking up 95-plus scrimmage yards for the third time in four games this season.
Henry has 8,620 career rushing yards and now trails only Eddie George (10,009) in team annals.
And, oh yeah, Henry can pass, too – he's 7-of-8 with three TDs and a 120.0 passer rating in his career.
3. DeAndre Hopkins Was a Good Get.
Hopkins leads the team in catches (18) and yards (216) through four games.
Hopkins is on pace to finish the year with 77 catches for 918 yards.
While those numbers won't approach career highs for Hopkins, his value to the team has been on full display for the Titans.
Hopkins, who owns the NFL's longest active streak with 149 consecutive games with a reception, has eight third down catches that produced a first down this season, which is tied for the most in the NFL.
4. The Run Defense is Still Solid
The Titans are ranked 1st in the NFL in rushing yards allowed per play (2.89 yards) and 4th in rushing yards per game (70.0).
On Sunday against the Bengals, the Titans defense allowed just 72 rushing yards on 18 attempts.
In doing so, the defense improved its streak to 10 consecutive games without allowing the opposing offense to reach 100 rushing yards.
The Titans defense also has gone 20 games without allowing an individual 100-yard rushing performance.
FOUR THINGS I STILL DON'T KNOW
1. How Good is This Team?
The Titans have been on a roller coaster ride this season – down, up, down, up.
The lowest point came in Week 3, when the Titans looked like pretenders in a 27-3 loss to the Browns. It was one of the poorest offensive showings in the Titans era.
Then in Week 4, the Titans looked like contenders in a 27-3 win over the Bengals.
Titans quarterback Ryan Tannehill knows his feelings on this squad, while others wonder.
"I'm not wondering anything," Tannehill said. "I believe in that locker room. I believe in the guys. I believe in what have and what we're building. Proud of the way we came to work throughout this week to prepare ourselves and look forward to doing the same thing next week."
2. How Will the Starting O-line Shake Out?
Tannehill has been sacked 16 times in four games this season.
Some weeks, he's been under siege.
Now, the Titans have some decisions to make.
Guard Peter Skoronski is edging closer to returning after missing the past three games following an emergency appendectomy. Nicholas Petit-Frere is eligible to return to action after the NFL reduced his gambling suspension to four games.
The Titans will do some o-line shuffling, it's just a matter of who … and when.
3. Will the Pass Defense Find Consistency?
The Titans looked solid across the board on defense against the Bengals, limiting the big plays against some dynamic playmakers.
But the Titans are going to have to prove they can do that week in and week out.
Through four games, the Titans are allowing 241.3 passing yards per game, which is 23rd in the NFL.
The Titans have allowed 12 passing plays of 20 yards or more this season, although they didn't allow a single one against the Bengals.
Plus, the defense has just one interception in four games (Amani Hooker's INT against the Saints).
The Titans need to prove they can be consistently good here.
4. How Good is the AFC South?
The AFC South has been the butt of jokes in the past.
No one was laughing with the Colts went into Baltimore and won, or after the Texans beat up the Steelers.
The Jaguars, of course, went into the season as media darlings.
After four weeks, all four teams in the division are 2-2.
The cream of the crop will rise to the top in the coming weeks.
