Defensive tackles from LSU don't just fall out of the sky into your lap: usually you will have to spend a high pick to acquire one.
Miami got fairly lucky here, as LSU's Anthony Johnson went undrafted, partially because of an underwhelming combine and partially due to a failed drug test in February, as reported by Fox Sports' Jay Glazer.
Both of those events obscured an otherwise stellar career at LSU, one where he made 16 starts and racked up 22 tackles for loss and seven sacks before leaving after his junior season.
He's also only 21 years old, which means he has plenty of time to mature. He probably would have been better served staying in school, but I'm not one to begrudge athletes for jumping to the pros when they feel they are ready, provided they understand the consequences of their actions.
Johnson is a boom-or-bust project, but in all likelihood he found himself on the right team. Defensive line coach Kacy Rodgers is one of the best in the business, and with Miami's depth at the position, there won't be any pressure on Johnson to start right away.
He has impressed many in Miami already. According to the Miami Herald's Barry Jackson, Johnson was the "most impressive of undrafted fins rookies." Jackson tweeted coach Joe Philbin's assessment as well: "He shows up on film."
Given his play thus far, Johnson might show up on the field too.
