Some rookies take little time to adjust to the NFL, such as last season’s AP Offensive and Defensive Rookies of the Year, Tetairoa McMillan and Carson Schwesinger.They were among several rookies that made major impacts in 2025, including Seattle’s versatile defender Nick Emmanwori, who helped elevate a defense that led the Seahawks to a Super Bowl title, top-10 pick tackles Armand Membou and Kelvin Banks, and pass catchers Tyler Warren and Emeka Ebuka.But failing to become a star in year one doesn’t mean a draft pick was wasted.Here’s a look at some players who showed promise as rookies in 2025 who now have a chance to break out and become stars in their second seasons in the NFL:Arizona DT Walter NolenNolen never really got started as a rookie, missing the start of the season with a calf injury and then getting shut down early with a knee injury. Nolen had flashes in his limited time in six games that showed why the Cardinals drafted him 16th overall. He had two sacks and 15 pressures in just 99 pass rush opportunities, according to Pro Football Focus, and also returned a fumble for a TD. If he can have close to that kind of production in more extensive time, he could quickly become one of the top pass rushing defensive tackles in the game.
