2019 Panini Prestige Football Alex Barnes autograph rookie card No. 284 Tennessee Titans. Barnes is a running back who played college ball at Kansas State University. He was with the Tennessee Titans to start his career but is currently a free agent hoping to catch on with another NFL team. Alex Barnes is a powerful running back that can also make defenders miss. My prediction is Barnes will get signed by another team and will eventually make a big impact in the National Football League.
