LB Colin Schooler is on an historic UA pace

Arizona sophomore middle linebacker Colin Schooler is tied for first nationally in tackles for loss with 2.5 per game.

Schooler came up with four stops behind the line in a 35-14 win at Oregon State on Saturday, giving him 10 on Saturday.

His total through four games would have been a team-high number for the Wildcats in 2016, 2015, 2011 and 2003, which says something about Schooler's hot start and about how bad UA some of UA's defenses have been in the post-Dick Tomey years.

"I feel like defensively we played really well," Schooler said in a postgame press conference. "We started to look like a unit ... and everybody's making plays."

With one-third of the regular-season completed, Schooler projects for 30 tackles for loss at his current pace (and that doesn't include a potential bowl game). The UA school record is 29, set in 1968 by Tom Nelson and tied by Scooby Wright in 2014.

--Arizona's 11 tackles for loss against Oregon State marked the team's best total since having 15 in a win over Arizona State in 2014.

--Redshirt freshman STUD linebacker Jalen Harris made a pitch for a lot more playing time with a career-high five tackles, including a sack, vs. the Beavers. The position demands edge-rushing skills, combined with the ability to drop into coverage.

Harris has been behind sophomore Kylan Wilborn, who drew the sideline wrath of coach Kevin Sumlin for a personal foul penalty when he shoved Oregon State quarterback Conor Blount out of bounds.

--Arizona is 110th in the nation in third-down percentage defense, allowing opponents to convert 44.9 percent.

Oregon State had drives of 17 and 13 plays in the second half in which the Beavers converted a combined 6 of 7 third-down opportunities, plus a fourth-and-1 chance en route to a touchdown.

Oregon State, on those two drives, converted third downs of 8, 8, 1, 4, 14 and 8 yards. The only opportunity it missed is when it faced third-and-32 after multiple holding penalties and a fumble.

"Let's be honest, that one drive, the score there in the fourth quarter, that's what it was all about," Sumlin said about third-down defense. "In a closer ballgame that could come back to bite us. We've got to be better there."

--JJ Taylor's 284-yard game vaulted him to 11th nationally in rushing at 119.3 yards per game.

--P Dylan Klumph punted once in the past two weeks, that coming in the first quarter against Oregon State. In the past two games, Arizona has had 23 possessions. This is how they have ended:

* 13 TDs

* 4 FG attempts (two made)

* 3 end of half

* 2 turnovers

* 1 punt

Yes, competition is going to get much more difficult, starting Saturday at home vs. USC.

--Arizona is 11th nationally in first downs (108), 15th in total offense (519.3 yards per game) and 19th in rushing (247.3).

--Arizona is tied for eighth nationally with nine plays from scrimmage of at least 40 yards, according to

--The Cats are tied for sixth in the country with six scrimmage plays of least 50 yards.

--QB Khalil Tate has rushed 65 times for 149 yards in the past seven games.
