Week 2 of the NFL regular season saw some players put up excellent performances in fantasy that weren't all that unexpected such as Ben Roethlisberger, Todd Gurley, and Michael Thomas. Just as there is seemingly every week though (including Week 1 [VIDEO]), there were players that put up impressive performances that were afterthoughts in fantasy heading into their games.

Here are the Week 2 fantasy football players who were likely unowned. Roto Baller lists nearly all of the players as waiver wire options for Week 3. Players who entered Week 2's games owned in less than 25 percent of ESPN fantasy football leagues were eligible.

Quarterback

  • Blake Bortles, Jaguars (377 passing yards, four passing touchdowns, one interception, 35 rushing yards)

Now in his fifth season, the oft-criticized Bortles picked apart the Patriots defense on Sunday. His 377 yards passing were the third most of his 64 career starts, and it was just the fifth time he threw for at least four touchdown passes (did it three times in the 2015 season). According to ESPN, he is just the third quarterback ever to put up at least 377 passing yards and four touchdowns in a game against Tom Brady.

Running backs

  • Corey Clement, Eagles (30 rushing yards, one rushing touchdown, five receptions, 55 yards)

Clement did work out of the backfield as a receiver with five receptions. It was the second time that the second-year back had more than one catch in his 18 career outings.

He scored on a 15-yard running play in the second quarter.

  • Tavon Austin, Cowboys (15 rushing yards, two receptions, 79 receiving yards, 1 receiving touchdown)

Eligible at both running back and wide receiver, Austin made much of his impact on the first possession when he hauled in a 64-yard catch-and-run for a score. It was the first touchdown for the former eighth-overall pick since October 8 of last year. The touchdown reception gave him more receiving yards than all of the 2017 season when he finished with 47.

Wide receivers

  • Tyler Boyd, Bengals (6 receptions, 91 receiving yards, 1 receiving touchdown)

Boyd caught just 22 passes in 10 games last year and had three in the opening week. Safe to say, he was on very few fantasy radars. His 91 receiving yards equaled a career-high for the third-year receiver, equaling the total he put up in Week 17 last year (his six receptions also tied his career-high).

  • John Brown, Ravens (4 receptions, 92 receiving yards, 1 receiving touchdown)

Brown finished his second season in 2015 with 1,003 receiving yards and seven touchdowns but totaled just 299 receiving yards in 10 games for the Cardinals last year. He has now found paydirt in his first two games as a member of the Ravens.

Tight end

  • Jesse James, Steelers (5 receptions, 138 receiving yards, 1 receiving touchdown)

James will likely be one of the more added players [VIDEO] after he has been targeted five times in each of the first two games. Now in his fourth season, his 137 receiving yards on Sunday easily surpassed his previous career-high of 97.
