Apparently, though, Seattle has no concerns about any of those issues.
"This is the kind of guy that puts fear in offensive tackles,'' Carroll said.
At least when he's on the field.
"Here's the deal with Irvin: He's a situational pass rusher only,'' Mayock said. "And that means that on run down he won't even be in the game. But because it's a pass-first league, he'll get more snaps than he would have five years ago.''
If all that Seattle asks of Irvin, though, is to rush the passer in that 4-3 scheme, the Seahawks might well have made a heady move. In his first year at West Virginia, 2010, he was second in the nation with 141/2 sacks despite never having been taught any real mechanics of the position and showing up only in time for August camp.
As a junior, with a bit more knowledge but still playing in a defense geared to stopping the run, his sack total dropped to 81/2, but that was largely due to double and triple teams. He also played in a league, the Big East, that didn't throw the ball as much as many others.
"I love eating quarterbacks,'' Irvin joked during Thursday night's call.
Where Irvin's stock really rose was in the NFL Combine in February. There he was by far the most physically impressive pass rusher, running a 4.5-second 40-yard dash and excelling in agility drills. He was equally as impressive at his pro day in Morgantown in mid-March.
Seattle's decision to take Irvin in the first half of the first round of the draft probably is equal parts due to those workouts and his relative infancy in the game. He didn't play football after his sophomore year in high school and has never been involved in a defensive scheme that emphasized the techniques of rushing the passer, either in junior college or at WVU.
"To be honest, I've never been taught how to pass rush,'' Irvin said last week. "My last two years, I had 23 sacks. I've had like 40 in three years [including junior college]. And I got it all on natural ability.''
Irvin becomes the first West Virginia player drafted in the first round since Pacman Jones in 2005, who was the sixth overall pick by Tennessee. He is only the ninth Mountaineer ever to be drafted in the first round.
