In the first two weeks of the season, it was Ryan Fitzpatrick of the Buccaneers who was the surprising talk of fantasy football. Starting for a suspended Jameis Winston, he threw for 819 yards and eight touchdowns in the first two games. While “Fitzmagic” came to somewhat of a halt in Week 3 as he threw three interceptions. He still ended with 411 passing yards and three touchdowns.

In Week 4, Fitzpatrick was benched for Winston and his quarterback counterpart on the opposing team, Mitchell Trubisky, lit the Buccaneers up with an astonishing game.

It’s no surprise that Trubisky is the quarterback for Week 4’s fantasy football stars who were likely unowned.

In order to make the list, the player must have been owned in less than 25 percent of ESPN fantasy leagues entering their game.

Quarterback

  • Mitchell Trubisky, Bears (354 passing yards, 6 passing touchdowns, 53 rushing yards)

Going into his 16th career start on Sunday, Trubisky had never thrown more than two touchdown passes (only did it once) in a game. He had just two in the first three games of the season. On Sunday, he threw his fifth touchdown pass with a little less than five minutes left in the second quarter to set a new franchise record according to Yahoo. He finished with six for the game, and his passing and rushing yards both set new career-highs. The Bears have plenty to be confident about as they start the season 3-1 [VIDEO].

Running backs

  • Mike Davis, Seahawks (101 rushing yards, 2 rushing touchdowns, 4 receptions, 23 receiving yards)

With Chris Carson a late scratch by the Seahawks, it was widely assumed that 2018 first round pick Rashaad Penny would receive the lion's share of the carries.

Instead, it was Davis who got the brunt of the work after he had just three carries for three yards entering Week 4. His two rushing touchdowns were twice as many as the one he had in his first 125 carries in his career which started in 2015.

  • Nyheim Hines, Colts (10 rushing yards, 9 receptions, 63 receiving yards, 2 receiving touchdowns)

A fourth round pick this year, Hines had been involved in the passing game but for minimal yardage. In the first three games, he secured 13 catches but only for 56 yards and no touchdowns. While his 10 rushing yards in Week 4 were slightly less than the 15 he was averaging entering the game, his 73 total yards were 21 more than any of his first three outings. He entered Sunday's game with one touchdown (on the ground) but scored twice in the second half on passes including one with 45 seconds left that helped send the game to overtime.

Wide receivers

  • Taylor Gabriel, Bears (7 receptions, 104 receiving yards, 2 receiving touchdowns, 10 rushing yards)

In the midst of Trubisky’s career game was an excellent performance by Gabriel [VIDEO].

He had 15 receptions in the first three games but for only 5.9 yards per catch and no touchdowns. Week 4 was the first time he went over 100 yards receiving and was just the second time he snagged two touchdown catches in his 62 career games. According to CBS Sports, he was targeted seven times, and each one resulted in a catch.

  • Donte Moncrief, Jaguars (5 receptions, 109 receiving yards, 1 receiving touchdown)

Moncrief wasn’t all that involved in the Jaguars’ offense in the first three games as he compiled seven catches for 64 yards. He surpassed his season yardage total with just one catch in Week 4, a 67-yard touchdown in the third quarter. His 109 receiving yards were his most since Week 12 of the 2015 season.

Tight end

  • Geoff Swaim, Cowboys (3 receptions, 39 receiving yards, 1 receiving touchdown)

A seventh round pick in 2015, Swaim only caught nine passes in his first three seasons with the Cowboys. He is finally becoming involved in the offense as he also caught five passes in Week 3. His third quarter touchdown reception was the first of his career.
