Amari Cooper looks like he ate Khalil Mack for breakfast

Oakland Raiders wide receiver Amari Cooper has been doing some serious work in the weight room ahead of the 2017 NFL season.

He showed up to camp on Sunday looking like he ate Khalil Mack for breakfast.

We sure hope that extra bulk doesn’t slow this kid down.

Remember, we’re talking about a young man who torched the track at the combine a couple years back, running the 40 in 4.42 seconds. He weighed in at 211 pounds at the time, which was plenty of weight for a 6-foot-1 receiver.

Now Cooper looks like he’s added another 10 pounds of pure muscle. If anything, his ability to run after the catch should frighten the hell out of defensive backs.
