Who the hell does he does he think he is?

Ok Im A Jets fan and i have never heard of this guy before this week. He has been talking alot of trash and stuff and i have never heard his name in my life. So forgive me if he is some superstar ,but i just had to go look at what position he plays and i found of he is a backup defensive linemen.

I know the Jets talk alot more than most teams ,but the people who talk back it up with their play. Has Brock done anything of impact besides a couple of sacks cause he is a lineman. Im just wondering?

Thanks
