The Missouri Tigers enter the 2018 season with high expectations after a dramatic second-half turnaround last year.

However, there are some noticeable differences with the roster, as DE Marcell Frazier, WR J’Mon Moore and some key players in the secondary are no longer with the team. Also gone is OC Josh Heupel, whose fast-paced offense led to several broken records in 2017. In his place is Derek Dooley, whose scheme will remain a mystery until Week 1.

Still, there’s reason for optimism this year, and even more records could fall. With a star QB like Drew Lock leading the offense, the Tigers should still put up plenty of points when they kick off the upcoming campaign on Sept. 1.

Here’s a look at five records that could be broken during the 2018 season:

1. Passing touchdowns (career)

Drew Lock has 71 touchdown passes, which is only 30 behind all-time Mizzou leader Chase Daniel. Considering Lock threw 44 touchdowns in 2017, 31 is not out of the question for 2018.

As long as Lock stays healthy, and continues to improve his play against the SEC’s top defenses, he should be a lock (pardon the pun) to take over the top spot in the Mizzou record books.

He showed last year that he could have success against Georgia’s defense, so while he’ll face tough tasks this year against Georgia, Alabama and others, he should continue to pile up some impressive statistics.

2. Total touchdowns (career)

Again, Daniel holds the record, accounting for an incredible 111 scores during his time at Mizzou. However, Lock is on his tail once more, entering the 2018 season with 75 total touchdowns.

That puts him 37 touchdowns from the mark, so another big year would put him ahead of Daniel in yet another spot in the Mizzou record books. Lock’s career breakdown looks like this — 71 passing touchdowns, 3 rushing and 1 receiving.

Assuming he won’t be showing off his hands again anytime soon, and assuming he won’t become a Cam Newton-like dual-threat quarterback this season, he’ll have to rely on another big year with his right arm.

3. Yards per carry (season, minimum 150 carries)

Alright, that’s enough about Lock (for now, at least). Next, we move on to the running game, where Damarea Crockett already holds the record for yards per rush (minimum 150 carries) in a season. In 2016, Crockett — then a true freshman — averaged 6.9 yards per carry.

Even last year, when he was limited by injury, he turned in an impressive 6.0 yards-per-carry average. This fall, he’ll share the load with Larry Rountree III, who emerged as a solid back in 2017, but if Crockett’s healthy, he’ll probably get a bulk of the carries.

He’s proven he can find plenty of holes to run through. Behind one of the SEC’s best offensive lines, and with Lock keeping defenses from stacking the box, Crockett should have plenty of room to do his thing.

4. Total tackles (season)

For the past couple of seasons, linebacker has been a position of weakness for the defense. This year, though, that should change, as senior Terez Hall and junior Cale Garrett are both returning to take a run at Travis McDonald’s record of 164 tackles in a single season, set back in 1994.

Garrett is the Tigers’ leading returning tackler, recording 99 to Hall’s 80 in 2017. Neither of those marks is close to McDonald’s record, but the Tigers’ defense let opponents score far too often last season.

If Dooley’s offense slows down the pace a bit, that should keep the defenders fresher. That, in turn, could lead to more tackles and fewer touchdowns allowed for Hall and Garrett in 2018.

5. 300-yard passing games (career)

We’ll throw one more Lock record in here for good measure, as he should have more than his fair share of mentions in the Mizzou record books by the time the 2018 season is done.

Lock already has the school record for most games with more than 400 passing yards, eclipsing that mark 5 times (to Daniel’s 4). But, Daniel still holds the lead in games with 300 or more passing yards, doing so 20 times.

Lock, to this point, has 10. It won’t be easy for him to reach (or beat) the mark set by Daniel, but it’s possible, particularly if the Tigers go to a bowl game.

For example, West Virginia QB Will Grier eclipsed the 300-yard mark 9 times last season, and probably would have done it a couple more times if not for breaking a finger against Texas. That caused him to miss the rest of that game (finishing with only 50 passing yards), the next week’s game against Oklahoma and the Mountaineers’ bowl against Utah.

If Lock can find some consistency, especially against top opponents like Alabama and Georgia (both of whom are rebuilding their secondaries), another record of Daniel’s could fall.
