Cooper has the numbers, Hayne don't.
Cooper set records in the hardest defensive division in college football and was picked at #4 in the draft. You're a superstar out the gate at that point, it's either up to him to put up the numbers or be a bust. He's putting up the numbers.
I know you're new to the NFL, but Cooper is in the same situation as guys I mentioned earlier, Calvin Johnson, Larry Fitzgerald etc. They were superstars from their first NFL snap. Nobody said "give them the season" lol
