The 2017 SEC on CBS slate began with TCU at Arkansas in Week 2, and the Horned Frogs got revenge for last season's double overtime thriller with a 28-7 win over the Razorbacks in their place.

What did we learn from the matchup? Let's look at three things we picked up from the game

1. TCU is a Big 12 contender: That wasn't your everyday, Big 12-style shootout. That was grown-up, SEC football in which the home-standing bully was pushed around by what was supposed to be the exotic, finesse team. The Horned Frogs ran well between the tackles all game, Darius Anderson topped the 100-yard mark and scored once, and they routinely got the offense in second-down situations of less than five yards. 

Consider that a statement to the Big 12. With quarterback Kenny Hill and a deep and versatile receiving corps, TCU is set up to play point-a-minute football if it has to. But it might not have to. The ability to win in the trenches and wear down opponents is another weapon for coach Gary Patterson's crew to use as it looks to get back to the top of the Big 12 mountain.

2. Kenny Hill continues to impress: No, the artist formerly known as "Kenny Trill" didn't throw a touchdown in the win, but he was the most important player in the field. He made smart decisions through the air, went through his progressions well and chose to tuck and run when windows opened on several occasions to keep the chains moving. He finished 21-of-31 for 166 very smart yards.

Can we get over the idea that Hill is the punchline who fizzled out at Texas A&M after a hot start in 2014? He's evolved into a smart quarterback, who still can be dynamic at times, but recognizes that his primary responsibility is to be smart and let the right playmaker do the work at the right time.

3. Arkansas is a mess: That was one of the ugliest games of coach Bret Bielema's five-year career in Fayetteville. No, it wasn't as shocking as the loss to Toledo in 2015 or as lopsided as the 52-0 loss to Alabama in 2013. But TCU lined up toe-to-toe and played better "Arkansas football" than Arkansas did -- in Fayetteville. They took the Razorback identity, and wore it like a custom fit, three-piece suit. That should be unacceptable. 

What's more, the move the 3-4 defense doesn't seem to be working out all that well. Anderson routinely got to the edge to gain extra yards, the secondary didn't cover well and linebackers didn't flow to the ball as well as they needed to. Bielema isn't on the hot seat, but in Year 5, his program should at least be in the conversation. That doesn't look possible after what happened Saturday afternoon.
