Week 7 college football picks, lines, odds, 2023 best bets from proven expert: This 3-leg parlay returns 6-1

LSU is lighting up the scoreboard on a weekly basis. The Tigers have scored at least 34 points in each of their last four games, averaging 49 points per game over that span. The No. 22 Tigers are 4-2 entering their home matchup against Auburn in an SEC West battle of the Tigers. Auburn had a chance to knock off No. 1 Georgia last weekend after scoring the game's first 10 points and tying the score at 20 midway through in the fourth quarter. The Bulldogs, however, put together a seven-play, 75-yard touchdown drive, capped off by a 40-yard touchdown with 2:52 left in the game in a 27-20 win to remain the top-ranked team in the country.

Can Auburn shake off that emotional loss against Georgia from just a week ago? LSU is an 11.5-point favorite in the latest Week 7 college football odds from the SportsLine consensus. Other key Week 7 college football spreads of note include No. 7 Washington (-3) vs. No. 8 Oregon, No. 10 USC (+3) vs. No. 21 Notre Dame and No. 12 UNC (-3) vs. No. 25 Miami.

Top Week 7 college football expert predictions

One of Sallee's top Week 7 college football picks: He's going Under in the USC vs. Notre Dame matchup at 7:30 p.m. ET in South Bend, Ind. The total has dropped to 60.5, though he locked it in at 63 earlier in the week.

With reigning Heisman Trophy winner Caleb Williams at the controls of Lincoln Riley's offense, the Trojans have been piling up eye-popping totals. They've scored at least 42 points in every game and they've cleared the 50-point plateau twice this season. USC, however, hasn't played any particularly strong defenses, and that changes against the Irish.

Despite playing a rugged schedule, Notre Dame ranks 15th nationally in scoring defense, giving up just 15.9 points per game. Sallee expects Notre Dame to take advantage of a weak USC defense by putting together long, sustained drives that keep Williams on the sideline. Combine that with lower expected numbers from USC's offense, and he's expecting the Under to hit with some room to spare. See what other picks Sallee likes at SportsLine.
