Who's going to take all the marbles?

The Indianapolis Colts host the Houston Texans in NFL Week 18 action, and the winner makes the AFC playoffs while the loser's season ends. Both teams are 9-7 and tied with Jacksonville Jaguars atop the AFC South.

A key to this game: Can the Colts get to Texans rookie quarterback C.J. Stroud? In the second half of the season, Indianapolis wins when sacking opposing quarterbacks at least twice but loses when the QB has time to operate. Also, Stroud is far less effective on the run as opposed to passing from the pocket.

Opinions on this game vary.

NFL Week 18 picks, predictions: Colts vs. Texans for an AFC playoff berth

Brooke Cersosimo, NFL.com, Texans 24-22: The last time these teams clashed was all the way back in Week 2, when the Colts prevailed 31-20. The Week 18 versions of these clubs are completely different, as Texans head coach DeMeco Ryans stated earlier this week. C.J. Stroud has proven to be one of the more consistent quarterbacks this season with a 21:5 TD-to-INT ratio, which leads all qualified QBs, per NFL Research. That consistency could be in jeopardy against a Colts D that pressured Stroud a season-high 25 times in their last outing. Not to mention, Stroud is 2-4 with just four pass TDs in road games. In my eyes, though, the Texans are the better team right now with a top-five run defense that should keep the Jonathan Taylor-led Colts' rushing attack at bay and an opportunistic pass defense -- albeit, a banged-up one -- that could make Gardner Minshew pay if he's not careful. Texans win. They’re in!

Sam Farmer, Los Angeles Times, Colts 23-21: Playoff and division implications for both teams. Quarterback C.J. Stroud has been so good for the Texans. This figures to be tight but Houston is pretty banged up and the home team is more experienced.

Mike Florio, Pro Football Talk, Texans 20-17: We finally get to see C.J. Stroud in prime time. That’s bad news for the Colts.

Ryan Reynolds, 33rd Team, Texans 27-20: C.J. Stroud returned to action last week, and he remains the favorite in the Offensive Rookie of the Year race. The Colts are giving up the sixth-most points per game this season. Houston doesn’t have a supremely talented roster, but neither does Indianapolis. Stroud is the biggest difference-maker on either team.

Vinnie Iyer, Sporting News, Texans 23-20: The Texans have C.J. Stroud back at QB to fire up their passing game again and also will be able to run well in this matchup. Gardner Minshew has been a game long-term backup fill-in all season, but he tends to be on a roller coaster with his efficiency and it's due to go down vs. DeMeco Ryans' scheming defense, which can start well by containing Jonathan Taylor.

Pete Prisco, CBS Sports, Texans 31-26: The winner of this game will be in the playoffs and could win the AFC South if Jacksonville loses to the Titans. The Texans are a different team with C.J. Stroud, who played well last week after missing two games. I think he plays a good game here and the Texans make the playoffs.

Gerry Dulac, Pittsburgh Post-Gazette, Colts 24-21: It’s very simple for each team: Win and it’s a possible division title or wild card spot. Lose and it’s go home. The Colts won the earlier meeting in Houston and have won their past three home games. The Texans got C.J. Stroud back just in time.

Neil Greenberg, Washington Post, goes with the Colts: On paper, Houston looks like the better team. The Texans’ net efficiency ranks 12th after adjusting for strength of schedule, per analyst Aaron Schatz’s defense-adjusted value over average, while Indianapolis is 19th. The actual gap between them (7%), based on historical data, suggests the Colts should be a slight favorite at home.

Indianapolis should also have an edge in the trenches, especially when facing quarterback C.J. Stroud and Houston’s passing attack. The Colts’ pass rush ranks ninth, per Pro Football Focus, while the Texans’ offensive line ranks 19th in pass blocking. Stroud performs worse under pressure, as do most passers — but his drop in production is severe. His passer rating declines from 110.3 when operating in a clean pocket to 71.9 when facing pressure, which corresponds to a decline from the sixth-best passer out of 24 qualified quarterbacks to the fifth-worst, per PFF grades.

Brian Blewis, Pro Football Network, goes with the Texans: By point differential and DVOA, the Texans have been a far better team than the Colts this season. Indianapolis has been overachieving all season long, but I think that comes to an end, even at home, in this Week 18 matchup.

The only concern here in taking the Texans is they’re a much worse team on the road than at home with C.J. Stroud under center — 2-4 compared to 6-2 in Houston — but that’s not scaring me off enough from taking the better team.

Albert Bainbridge IV, Bergen Record, takes the Texans: With Stroud back under center, I believe Houston takes advantage of a Colts defense that’s surrendered the sixth-most points per game (24.5 PPG) this season and has allowed 28 or more points in three of their last five.

Jim Derry, NOLA.com, Colts 26-24: There might not be a more cool story in the NFL this season than the Houston Texans, who have proved a whole lot of people wrong that they couldn’t turn things around right away with CJ Stroud and DeMeco Ryans.
