So far, everyone has seemed to want to talk about Oakland Raiders pass rusher Arden Key's weight. He doesn't mind, since it beats talking about how his team averaged less than a sack a game last season.

Key had a frustrating rookie season, coming in at 238 pounds and battling a shoulder injury. The 6-foot-5 Key had shoulder surgery in January — he injured it in training camp last summer — and said he has put on 15 pounds, from 245 to 260, the last two months.

Key had to learn on the fly last season after the trade of Khalil Mack forced him into a larger role than expected. So far, this offseason has been good. He's healthy, and better.

He is working with (new defensive line coach Brentson) Buckner on getting both of his arms free when he gets around the tackle, as that will help him make the play and get the quarterback down.

Yeah, that’s all Buck been teaching me, as far as my angle,” Key said. “He started (the reel) off with, I missed (that) sack just by my alignment. The ball isn’t snapped yet (but) I just missed the sack already by my alignment.”

“Whether I was too wide, too tight, I didn’t turn my hips enough or I didn’t reach for him, turn my hips and different things like that. Most of it was just alignment and knowing what angles to take. Football is all about angles.”

Getting stronger and generating power has also been been the focus. Key came into the league small at under 240 pounds. With added weight and strength, Key could be in line for a big season.
