At this point, you have to give the benefit of the doubt to Marvin and Mike Brown. The Bengals were criticized for picking up Benson, taking back Henry, signing Tank Johnson, keeping Chad, etc. I mean, come on already. The Bengals are 7-2 right now, and every one of those guys have been critical to that success. Not only that but when Tank went down for a few weeks, people were itching for him to come back and add to the depth chart. Not to mention how many people were upset with Henry going down. These were two guys that nobody wanted the Bengals to take. Now they sign Larry Johnson and its the same old story.
The guy was a former pro-bowler. He ran for 4.5 yards per carry last year on a terrible team, and he was dissatisfied with his team (as Chad was with ours for the last 2 years). He is coming to a whole new environment, a rejuvenated locker room, and he has yet to be included in any kind of game plan. If he acts up, which everyone should be hoping he does not, then he is gone, simple as that.
Until then, you have to give LJ the benefit of the doubt. He wants to win, we are winning. End of story. The coaching staff will not put up with his antics. Let him be a positive piece to the puzzle and give him your support.
If the rest of the team supports him, there is no reason why you should not.
