JACKSONVILLE, Fla. -- Jaguars quarterback Blake Bortles followed up one of the best games of his career with one of his worst in the Jaguars’ 23-20 overtime loss to the Jets. Bortles completed 42.9 percent of his passes, which is the second-lowest completion percentage of his career, and threw an interception deep in his own territory.

Even so, the Jaguars still had a chance to win the game in overtime had Marqise Lee not dropped a third-down pass that would have put the Jaguars inside the Jets’ 30. That was perhaps the best throw Bortles made all day, too.

Bortles’ inconsistency means the Jaguars are likely going to have to look for another quarterback in 2018. It’s a good thing that the 2018 quarterback draft class is projected to be one of the best of the past decade.

Some early draft projections have as many as five quarterbacks being taken in the first round. Here’s how five of the top prospects -- generally regarded among the top collegiate quarterbacks who could be first-round picks -- have fared so far this season:

Josh Allen, Wyoming

Allen shook off a rough start to the season by throwing for 219 yards and three touchdowns in the Cowboys’ 45-10 rout of Texas State. Allen threw for 151 yards and two scores as part of Wyoming’s 31-point second-quarter. However, it’s still worrisome that he completed little more than 50 percent of his passes against a subpar opponent (14 for 24). Allen had thrown only three touchdowns in his first four games.

Season stats: 77 of 139 (55.4 percent), 877 yards, six TDs, three INTs.

Sam Darnold, USC

Rough night for Darnold in the Trojans’ 30-27 loss at Washington State -- the first victory for the Cougars in the series since 2002. Darnold completed 15-of-29 passes for 164 yards and one interception and ran for two more scores, but he also fumbled when he was sacked deep in WSU territory with less than two minutes remaining. Darnold didn’t have three starting offensive linemen for much of the game and was battered and harassed by the WSU pressure pretty much all day. Darnold has thrown eight interceptions in five games this season, which is one shy of his total in 2016.

Season stats: 113 of 175 (64.6 percent), 1,389 yards, nine TDs, eight INTs.

Lamar Jackson, Louisville

Jackson didn’t play a full game for the second week in a row, this time leaving one play into the second half of the Cardinals’ 55-10 rout of Murray State. Jackson threw for 249 yards and three touchdowns and ran for 100 yards and a touchdown on only seven carries. He has thrown for 548 yards and six touchdowns and run for 134 yards and two TDs in the past two weeks. The Cardinals have beaten Murray State and Kent State by a combined score of 97-13. This week will be tougher for Louisville, which plays at NC State.

Season stats: 112 of 175 (64.0 percent), 1,636 yards, 13 TDs, three INTs; 72 carries for 437 yards and five TDs.

Josh Rosen, UCLA

Rosen surpassed 350 yards passing for the fourth time in five games, throwing for 372 yards and a touchdown in the Bruins’ 27-23 victory over Colorado. Rosen’s only interception came when he threw into double coverage, but it was an otherwise strong performance from the nation’s leader in passing yards and touchdown passes.

Season stats: 159 of 245 (64.9 percent), 2,135 yards, 17 TDs, five INTs.

Mason Rudolph, Oklahoma State

Rudolph accounted for five touchdowns in the Cowboys’ 41-34 victory over Texas Tech, including the game-winner on a 16-yard run with 1:12 to play. Rudolph threw for 376 yards and three touchdowns and ran for 50 yards and two touchdowns. Rudolph has thrown for at least 303 yards in every game this season.

Season stats: 117 of 173 (67.6 percent), 1,909 yards, 16 TDs, four INTs.
