Laporta is under control for two more years. You would only be gaining two more years of cap savings. With Laporta's draft class, you have an extra year before you would have to extend Gibbs and Campbell. As long as the Lions don't get caught up in signing overpriced free agents, they will be fine. By the time a new contract kicks in for Laporta, St Brown will be in the last year of his. You can always do a re-structure or re-sign him to a new deal that saves cap space.
