Entering the NFL, highly drafted rookie quarterbacks naturally command plenty of attention. They're the fresh, new faces at the league's most important E-40 Jersey position. That comes with intrigue and curiosity.But don't forget about the second-year pa sers. They're the ones who've tasted the league but haven't yet fully established themselves.And in the case of 2024's sophomore cla s the ' , ' , ' and the ' we have the full gamut of young quarterback experiences represented.Here's what each of them must do in his second season to be considered a succe s:ADVERTISEMENT C.J. Stroud2023 stats (15 games): 63.9% completion rate for 4,108 yards, 23 TDs, 5 INTsGoal: Maintain excellenceThe Texans don't need Stroud to take an astronomical leap in Year 2 (though after a historic rookie season, that doesn't feel totally implausible). They have enough talent to where even incremental improvement from Stroud should, in theory, keep Houston on track to become an AFC powerhouse.The team added perennial Pro Bowl wide receiver to a loaded pa s-catching corps that already featured , and tight end , all of whom have a year under their belt with Stroud. The Texans run game should also be better with free-agent addition . Coupled with the defensive reinforcements Houston also added in free agency (, and ), consistency not exponential growth should suffice for Stroud, who has become a more vocal presence on the team.But Stroud won't catch anyone by surprise in 2024. How will he respond to the adjustments made by defenses that now have a season's worth of tape of him?Stroud's rapport with Diggs will also be one important connection to watch. The quarterback must figure out how to most effectively split the target distribution between three No. 1-caliber receivers (Diggs, Collins, Dell). According to reports from local media, Diggs has been Stroud's most-targeted wideout in training camp practices.C.J. Stroud "wants to be like Eli Manning and not Aaron Rodgers" Anthony Richardson2023 stats (4 games): 59.5% completion rate for 577 yards, 3 TDs, 1 INT; 25 carries for 136 yards, 4 TDsGoal: Stay healthyDue to a season-ending shoulder injury in Week 5, Richardson played just 173 snaps as a rookie. Having him on the field for all 17 games (and potentially more in the playoffs) is objective No. 1 for the Colts. That's when they'll truly know what they have in Richardson, the most athletic quarterback prospect to ever test at the NFL Combine.Despite a poor completion rate in limited action last season (59.5%), Richardson's upside was evident. The arm strength was there. The dual threat prowe s was, too. He put the Colts on his shoulders in last season's Week 4 showdown against the , engineering a 23-0 run to force overtime in what was an eventual lo s. He became the first quarterback in NFL history to rush for a touchdown in his first three career starts.Staying healthy could mean rapid growth for Richardson, too. He has started just 17 games since high school. He showed league observers as a rookie that he wasn't as raw as initially believed, but he's still very inexperienced. More playing time could do wonders for his development and confidence po sibly more so than any other quarterback on this list.Richardson's upside is as great, or greater, than that of any pa ser in the league. Arthur: Trainer: Colts QB Anthony Richardson looks better than hes ever looked Bryce Young2023 stats (16 games): 59.8% completion rate for 2,877 yards, 11 TDs, 10 INTsGoal: Get in sync with new coach Dave CanalesFor Young's season to be considered a succe s, and to avoid speculation in spring 2025 that the Panthers could move in a different direction after just two years, he must be in lockstep with Canales.Of course, there was a lot out of Young's control as a rookie. Coach Frank Reich was fired after just 11 games. The offensive line play, particularly on the interior, was terrible. The wide receiver room was below average. The former star wasn't in a situation conducive for a rookie quarterback to have succe s. But Young also took a lot of bad sacks and was one of the league's least-efficient pa sers.As the offensive coordinator last season, Canales guided to a career season, which resulted in the veteran QB's three-year, $100 million extension in March. The year prior, Canales was the quarterback coach, helping to a resurgence and big-money deal of his own.Young's goal should be to follow in the footsteps of Mayfield and Smith. He needs to gain mastery of Canales' system in a way that enables him to rediscover the greatne s that made him the consensus No. 1 overall pick in last year's draft.Will Levis2023 stats (9 games): 58.4% completion rate for 1,808 yards, 8 TDs, 4 INTsGoal: Take advantage of revamped supporting castLevis, entering his first season as the full-time starter, has the opportunity to show the Titans bra s that he can be the long-term solution at quarterback. To do so, he must maximize what's at his disposal: new coach Brian Callahan's pa s-friendly scheme and a significantly improved cast of weapons and protection.Gone are the excuses that the Titans have a -dependent wide receiver room and a subpar offensive line. Tenne see added and as targets, giving it one of the top wide receiver trios in the league on paper. The floor of the Titans' O-line has also improved significantly with the additions of No. 7 overall pick J.C. Latham and free-agent center Lloyd Cushenberry, as well as position coach Bill Callahan, one of the most respected offensive-line coaches in NFL history.The early hiccups of Levis' connection with Ridley is one thing that must be shored up come the regular season for the quarterback to earn the trust of the franchise.Can Will Levis lead the Titans to the playoffs? Arthur: Titans QB Will Levis, new WR1 Calvin Ridley struggling to connect consistently Last season, Levis' completion rate ranked the worst among all qualified quarterbacks. But Tenne see's wide receiver talent and having two running backs who can catch out of the backfield in Tony Pollard and Tyjae Spears should help the former Kentucky star improve his completion numbers if he properly takes advantage of them.Ben Arthur is the AFC South reporter for FOX Sports.
