In dynasty fantasy football leagues, managers often overlook veteran players as they quickly look to cut aging assets. However, certain running backs still hold significant value and can bolster a team. Joe Mixon, now with the Houston Texans, had a solid season, but his advanced metrics raise concerns about his efficiency as he approaches age 29. Selling him for rookie draft capital could be wise. Tony Pollard of the Tennessee Titans also had a decent year but struggled with efficiency and may see competition from Tyjae Spears. Selling him could prevent a drop in value.

James Conner of the Arizona Cardinals had a career year but faces injury concerns as he turns 30 soon. If not contending, trading him should be a priority. Alvin Kamara remains productive, yet his metrics suggest decline as he enters his 30s. Lastly, Saquon Barkley's stellar season raises his value, making him a prime sell-high candidate. While he still performs well, the risk of injury looms large, and capitalizing on his current market value is smart.
