As Profootballtalk.com noted, NFL teams have a strict limit on the signing bonuses that can be given to undrafted free agents. However, they're not limited in the salaries or guarantees made to the undrafted rookies. Leading the way this offseason is Strong. He got $320,000 guaranteed from the Eagles. Strong was once expected to be a high-round draft pick in this class but never heard his name called. He'll join a quarterback room in Philadelphia that includes Jalen Hurts, Gardner Minshew and Reid Sinnett. In 2021, Strong put up big numbers, throwing for 4,175 yards with 36 touchdowns and just eight interceptions. He also completed 70 percent of his passes for two straight seasons. So why was he available as a UDFA? Well, he doesn't move very well. In fact, NBCSports.com contends Strong is "a sitting duck" with a long history of injuries to his right knee requiring multiple surgeries dating back to high school. With that said, Strong does have the desired quarterback frame and a big arm with the ability to fire passes deep and into tight windows. And he could have big upside as a UDFA. The Eagles have Hurts as their starter and Minshew as their backup for now. But there's always a chance the opportunistic Howie Roseman will ship away his backup quarterback before the season, which means there could even be a path for Strong to compete for the No. 2 job at some point.
