WACO, Texas — Describing David Montgomery's running ability can be difficult, and even Iowa State coach Matt Campbell has struggled to provide adjectives to illustrate it.

Luckily, PFF College has helped define it.

Entering the weekend, Montgomery was just one forced missed tackle away from tying the single-season record in the PFF College era dating back to 2014. Montgomery's 88 forced missed tackles led the nation by quite a margin, and the sophomore only extended his lead with 13 more forced missed tackles on 27 carries in Saturday's 23-13 win against Baylor.

Montgomery now has 101 forced missed tackles this season to claim the record.

That's pretty good company, even if the stat is only four seasons old.

“You know how I feel about him. He’s as good as there is in a lot of ways. He put the team on his back," Campbell said of Montgomery. "I thought the offensive line, I haven’t bragged about them very much but I tell you the last three weeks they’ve started to play some really good football. That group has done some really good things and obviously I think David would be the first one to tell you that too. David’s ability to break tackles and do what he does, I mean, it's what makes him really special."

Through 11 games, Montgomery's forced missed tackle rate is an eye-popping 38.3 percent according to PFF College, well above the national average of 17.2 percent. His 101 forced missed tackles this season have come on 264 total touches (230 runs and 34 receptions).

According to PFF College, roughly 690 of Montgomery's yards have come after contact.

Montgomery rushed for 144 yards on his 27 carries Saturday, enough to become the 14th player in program history to eclipse 1,000 rushing yards in a season. He now has 1,080 rushing yards on the season and 1,362 all-purpose yards with one regular season game remaining if he's healthy enough to play after X-rays came back negative on the left ankle he injured in the fourth quarter Saturday.

Regardless, he's now quite possibly the most elusive running back in college football.
