Chad Johnson blamed a portion of his lackluster tenure with the Patriots last season on the "suffocating air" in Foxboro last week. The receiver seems like he is liberated in Miami. On HBO's "Hard Knocks" Johnson was back to his usual ways, showing up late to team meetings and making the team about him. However, it appears new head coach Joe Philbin has put Johnson's personal renaissance on hold.

"I don't do media anymore," Johnson told USA Today to said after the Dolphins' Wednesday walkthrough.

Dick Ebersol is NBC Sports' former chairman and is currently acting as a senior adviser for the network's Olympics coverage. He talked to Joe Posnanski about the criticism that everyone and their dog is giving the network for its coverage from London thus far.

Needham’s Aly Raisman already had one gold medal from the team all-around event last week, and she added another two after winning gold in the floor exercise and a somewhat controversial bronze on the balance beam on Tuesday. The two competitions were her final events of the London Olympics.

The new look will feature a blue ribbon, to show support for victims of child abuse, and players' names on the back of the jersey to laud their loyalty to the program in the face of a four-year bowl ban. 

Last week President Obama said he was skeptical of the Jets decision to bring in Tim Tebow. The POTUS is not alone. On his radio show Monday, Boomer Esiason suggested Gang Green should cut ties with Tebow before he even settles in.

"If I was the Jets you want to know what I would do? I would cut Tim Tebow. I really would," Esiason said. "I'm telling you right now I would, and I'll tell you why I would: it's just not in any way, shape or form benefiting this team. I just don't see how it benefits this team.

Although Paul Pierce said he was "bitter" about Ray Allen joining the Heat, he saw how the Celtics treated Allen as a commodity last year, and talked about playing out his contract rather than seeking an extension. Pierce didn't allude that he wanted to leave Boston, he just wants flexibility. After all, Pierce said, the excitement of free agency is something he has never truly experienced.

President Obama lists everything great about Tim Tebow: a winner, clutch and, of course, a "wonderful young man." But, like others, the Prez is lukewarm on the idea of the Jets acquiring Tebow because of the inherent quarterback controversy that comes along with him.

The men's United States basketball team defeated Nigeria, 156-73, establishing a new high for points in an Olympic competition. Carmelo Anthony scored 37 points in 14 minutes and made 10 of 12 3-pointers, while surpassing Stephon Marbury's 31 for most points scored by an American in the Olympics.

Gabby Douglas became the first U.S. gymnast to win an individual and team Olympic gold medal as she captured the all-around title with her performance Thursday in London. Needham's Aly Raisman rallied in her final event to tie for third place but lost the tiebreaker and missed out on the bronze.

Douglas, the third straight American to win the Olympic all-around title, took the lead in the first event and stayed there, finishing with a score of 62.232, less than three-tenths better than Russian Viktoria Komova.
