Tyson Jackson and Paul Soliai were much-maligned after 2014, and with good reason. Both were well paid, and despite their presence in the middle of the Falcons' defensive line, Atlanta still had one of the worst run defenses in football. While Jackson's 2015 prospects with the Falcons are certainly up for debate, Soliai's are not.
Why? Simply put, the veteran defensive tackle does one thing well, and he wasn't necessarily any less effective at that than usual in 2014. Soliai was more of a victim of the Falcons' poor defense around him than the reverse, and it's why I fully anticipate the Falcons penciling him in for a fairly major role in 2015.
