The San Francisco 49ers are going to need Dee Winters to take a step forward next year. The former sixth-round pick is entering the most important season of his career, and while there is a question about how he will perform, his teammate Fred Warner has nothing but the utmost confidence. Whether or not Winters does take that step is going to have a massive impact on what the 49ers defense looks like this season. Winters spent his first NFL season behind Dre Greenlaw, and last year he spent the majority of the year behind DeVondre Campbell.
