Rob Gronkowski will play with a chip on his shoulder this week against the Detroit Lions. It's not unusual, but it does come with an explanation.The NFL this week fined Gronkowski, a New England Patriots tight end, $8,268 for a Week 11 play in which he Devon Kennard Jersey blocked Indianapolis Colts safety Sergio Brown off the field and out of bounds.PICKS: David Steele | Vinnie Iyer | Fantasy Source | The LinemakersIt was Gronk's job to deliver blocks to clear room for running back Jonas Gray, who ran for 199 yards in a 42-20 victory. But on the play in question, game officials decided Gronkowski went too far. They penalized him for unnece sary roughne s. League disciplinarians agreed and hit him in the Geno Smith Jersey wallet.Gronkowski told CSNNE.com he had had enough of Brown during the game. "He was just yappin' at me the whole time," Gronk said. "So I took him and threw him out of the club."That was in addition to a 26-yard touchdown catch-and-run in which he bulled his way through defenders. A week earlier, Gronk made a one-handed grab that sent jaws dropping and eyes popping.The Lions know they can expect Gronkowski to be a game-changing presence on Sunday. Ticking him off won't make things easier."He's a huge weapon for them," Lions quarterback Matthew Stafford told MLive.com. "They line him up all over the place, he Keenan Robinson Jersey runs every route in the route tree. Obviously, he's a size matchup for anybody smaller than him, which is pretty much everybody. He's quite often a speed matchup for linebackers and sometimes even safeties, so he's a dynamic weapon for them."Gronkowski is back at full health following a broken arm, a blown knee and back surgery, plus a Dalvin Tomlinson Jersey nasty infection that took time to clear up. He has been a beast during the Pats' six-game winning streak. His numbers, 40 catches, 587 yards and six touchdowns, don't account for his exceptional blocking ability.Given what he did to the Colts' Brown, the Lions don't need to be given any clues.
