#23. Tennessee Titans: Marcus Mariota & Antonio Andrews
Despite playing in just 12 games, Mariota shined in his rookie campaign. The former Heisman Trophy winner completed 62.2 percent of his passes with an average of 7.6 yards per attempt, with 19 touchdowns and 10 interceptions. He also rushed for 252 yards with an average of 7.4 yards per attempt, proving himself more than worthy of being the No. 2 overall pick in the 2015 draft.
After appearing in just four games in 2014, Andrews broke out this season as the team’s primary running back. He had 520 rushing yards and 174 receiving yards, ranking as the 25th-best running back in the league, according to PFF.
