What we saw from Brock today was a pocket awareness and understanding the situation that we haven't seen out of Tannehill. He wasn't sacked once, despite coming up against Kahil bloody Mack, and the 2nd ranked sack defense in the league. The Line played a big part in that but Brock too takes credit for extending plays and intelligently throwing the ball away (when will Tannehill learn how to do that ?). He always converted 50 % or so of our 3rd downs, it's been a huge problem for us for goodness knows how long. Arm talent and physical attributes to play the position, it's not even close, Tannehill is way superior. However for the game inside their heads, Tannehill just doesn't seem to get it, Brock today showed a way better command.
