Ref's did not beat the Jags. Yes the end of first half PI was baloney, as well as the PF call on the Gronk hit. It was clear Mack was going for the ball with his shoulder, and the heads collided due to collision. Still, that didn't lose the game.
What lost the game for the Jags was going way to conservative in the 2nd half, trying to sit on a 10 point lead, and the def. not stepping up and stopping a 3rd down and 18 late in the game.
Overall, the Jags played a great game, just couldn't finish it.
