Barmore is from Philly so I started reading a little bit more local stuff about him and he has a pretty interesting story. Never played football until his junior year when a coach yanked him off a basketball court and got him to try out, that charter school then closed so he had to transfer and play somewhere else his senior year. Started out the year only with offers from Buffalo and Temple but a few months later had offers from Alabama, Georgia, and others. He says that he taught himself to play by watching youtube videos of Reggie White, which is kind of ridiculous, but obviously he was raw as hell for a kid going to a program like Alabama.
Given that high school background, his trajectory at Alabama seems pretty decent - redshirt, part timer as a redshirt freshman, starts his redshirt sophomore year as a rotational player but grows more dominant and influential as the year goes on.
