After he fell in love, that is.
Sure, Allen only had Miller for one season, his rookie campaign, but what a year it was. Miller was the NFL's defensive rookie of the year after racking up 11.5 sacks and forcing four fumbles with Allen as his defensive coordinator.
"Absolutely, I saw a lot of similarities between him and Von Miller," Allen said of Mack after the Raiders selected him with the No. 5 overall pick Thursday night.
"And the thing that really was attractive about Khalil Mack was the fact that he understands how to rush the passer. And he understands how to rush the passer with power."
Mack, recruited by only two colleges out of high school, was the MAC's defensive player of the year last season after recording 10.5 sacks with 19 tackles for a loss. In fact, his 75 career tackles for a loss are the most in FBS since the statistic was tracked nationally in 2000.
Still, the furthest West he ever played in college was in the Famous Idaho Potato Bowl in Boise, Idaho, to end his college career. Before that, it was at Baylor.
"The conversation was crazy," Mack said of the call he received when the Raiders tabbed him. "I started on the phone with an assistant or a scout, and then I got on the phone with Reggie McKenzie, and then Dennis Allen told me how he wants to use me. It's a blessing to have this opportunity. I'm going to make the most of it."
Mack was not aware yet of the Miller comparison, but he was excited to join the likes of new Raiders defensive end Justin Tuck.
"Justin Tuck, man, how about that?" Mack said. "Playing with him is a blessing. Knowing how good he is and what he's done, it'll be good to learn from him. I can't tell you how excited I am."
Mack would appear to be a natural fit at weakside linebacker in the Raiders' 4-3 base defense, potentially making veteran Kevin Burnett expendable. But while Allen would not comment on a specific role for the rookie yet, McKenzie said Mack would have an immediate impact. Especially with the Raiders having an NFL-low 12 sacks with four or fewer pass-rushers last season, per data from ESPN Stats & Information.
"The guy has the size," McKenzie said. "He has the length. He's got speed. He's a playmaker. We'll find a way to put him on the field and get some production out of him."
Added Allen: "He'll have his hand on the ground some, too. I envision his role being very similar to what we did with Von Miller."
The Raiders are banking on similar results.
