Dallas Cowboys WR Amari Cooper says he’s not a top-five NFL receiver — at the moment. ‘It’s something I think I can prove this year, not sure if I’ve proved it yet, but I plan on doing it this year,’ Cooper told USA Today Sports’ Trysta Krick. ‘I think I definitely have the mentality and skill set to be a top-five receiver, that’s no doubt. But have I proven it? I don’t know. I really want to set out and prove it.’
