That list goes on and on. Ive had more intelligent conversations with a wall than you ever will have with rob gronkowski or chris johnson. You could ask chris johnson what 1+1 is and the only thing he'd have to say is "i can run real real fast"
Hmmm, yea, speaking of dumb players working out, How did Lawrence Phillips, Bam Morris and Maurice Clarett work out? And, yea, Gronk is a Pgh meathead but we aren't talking the level of stupid as others. And just watch: Gronk's career will not go as well as you assume. He will constantly be injured probably because his use of PEDs. If you wonder how he can be so big and fast - and brittle - there is your likely answer.
