COLUMBUS, Ohio -- Nick Bosa joked during training camp that he had started to feel like his brother last spring.

The Ohio State sophomore defensive end had grown accustom to the speed of the college game, gotten stronger and added moves to his arsenal -- a breakout season, he felt, was coming.

He might have been onto something.

Ohio State's defensive line was good in general, great, in last week's season opener against Indiana. If it weren't for quick throws from Hoosiers quarterback Richard Lagow, the Buckeyes would have racked up the sacks -- a point of emphasis for them this off-season. They finished with five sacks, and bottled up the Indiana run game (0.6 yards per carry).

With the No. 2 Buckeyes hosting No. 7 Oklahoma on Saturday night, Ohio State's defensive line looks most ready for the task of stopping Baker Mayfield and that high-flying offense. The rest of the defense? Still playing a little bit of catch-up.

Bosa looks ready. That might sound strange when you notice he had just one tackle, a sack in the first half. But he played more snaps (62 of 95) than any Ohio State defensive linemen, and looked like the improved player he said he was

* Bosa's speed around the edge was a problem, no matter which side he lined up on. On this play he basically runs around the left tackle, and forces Lagow to step up in the pocket where he's stopped by Tracy Sprinkle for a one-yard loss. Opponents will always get the ball of quickly against the Buckeyes' defensive line. It's plays like this we need to be paying attention to when evaluating them, not the sack totals.

Speed moves like this will prove a little more difficult next week when Bosa is matched up on Oklahoma left tackle Orlando Brown, an All-American candidate and one of the top tackle draft prospects in the country.

* Bosa will spend more time outside this season after playing inside a lot in the Rushmen package that puts all four defensive ends on the field. That was the case on Thursday, the majority of Bosa's snaps came with him lined up on the edge. But he looked like a capable run-stuffer lined up inside on this play.

Jalyn Holmes gets the stop with a great initial burst that leaves him un-blocked, but Bosa also made a strong move inside to wall-up the middle of the line and cut-off the designed point of attack. You also might have noticed Ohio State had five defensive linemen on the field for that play. More on that below.

* Part of Bosa's expanded arsenal of moves includes using his inside arm to essentially tip a lineman over. Joey Bosa used that perfection, and Nick seems to have it down. He's lined up on the left tackle here, and dumps him, collapsing the pocket and forcing Lagow into a hurried throw and incompletion.

* The best work defensive line coach Larry Johnson does with his players is his work with their hand fighting. It's what made Joey so advanced during his rookie NFL season, and it's what Nick uses here on his sack in the second quarter. The tackle can't get his hands on Bosa, who again uses his speed on an outside rush and trips up Lagow.

* Bosa, lined up over the right tackle here, can get it done with inside moves too.

Here are more notes on Ohio State's defensive line from the opener against Indiana:

* Bosa led all defensive linemen with 62 snaps, followed by end Jalyn Holmes (60), end Sam Hubbard (55), tackle Dre'Mont Jones (54), end Tyquan Lewis (45), tackle Tracy Sprinkle (35) and tackle Robert Landers (24).

* Ohio State used 12 defensive linemen in total with tackle Jashon Cornell (14 snaps), and ends Jonathon Cooper (14) and Chase Young (13) part of the game plan before things got out of hand. Tackles Davon Hamilton (6) and Haskell Garrett (6) got in for the final drive.

Note: Snap counts should be considered unofficial.

* The Buckeyes used those 12 defensive linemen in 24 different combinations.

* The most-used of those combinations was Ohio State's Rushmen package that includes all four starting ends: Bosa, Holmes, Hubbard and Lewis. That look was used 17 times.

* Ohio State did use a five-man defensive line look against Indiana. That included Hubbard and Holmes on the ends (sometimes standing, sometimes down in a stance) with Bosa, Jones and Lewis lined up inside. The Buckeyes opened the game with this look, and used it eight times -- all in the first half.
