The football world may not have heard the last of Michael Sam afterall.

At least not if the former Missouri defensive end can be believed.

Sam has drifted from the public eye as his quest to become the first openly gay player in the NFL faltered.

Drafted by the Rams, he was cut in 2014 without playing a regular season game. Then he was signed and released from the Cowboys practice roster. When no other NFL teams showed interest, he ended up with Alouettes last spring.

That never worked out either and Sam walked away for reasons never fully explained, although he claimed he wasn’t improving as a player in the CFL. Others suggested he left because he didn’t have the talent, or desire, to play in the CFL.

He disappeared from public dialogue. But this week on Twitter, speaking about resuming his playing career, Sam said “I’m going to give it one more shot.”

But where and when, after an uneven performance at the NFL veterans combine, remains a question.

Sam might want to give it one more shot. But teams are going to wonder if the hassles out-weigh any potential benefits. After walking away from Montreal, there might not be anyone willing to give him one more shot.

BIG MOVE LOOMING?

Jerry Jones is a firm believer in going big; or go home.

Lately that has meant spending a lot of Sunday afternoons at playoff time on the living room couch.

But it has never stopped him from making the headline-grabbing move.

So the football world is curious to see which high-profile quarterback he’ll try to hook up with.

Former Cowboys’ quarterback Troy Aikman believes he has the answer.

“I believe, as I sit here today, either Johnny Manziel or Robert Griffin III will be in Dallas as a backup,” Aikman told SI.com.

Either would fit Jones perfectly. He is a free agent’s best friend. One with experience such as Griffin might suit him perfectly. And, its apparent the Redskins will release him rather than pay his $16..2 million option.

Dallas badly needs a backup. Over their last 36 games, the Cowboys are 17-5 with Tony Romo and 1-13 without him. The question is whether Griffin can find another team where he has a better chance of moving into a starting role.

Manziel's best option might be to land behind a veteran like Romo; someone he can learn to be a leader from as well as a pro quarterback. Manziel is expected to become available when the Browns finally get around to cutting him loose for being more trouble off the field, than he’s been worth on it. Jones had to be talked out of drafting him in the first place. It’s unlikely he’d be talked out of a chance to sign him a second time.

BACK TO WORK

It’s back to work for the Carolina Panthers.

The NFC champions were back on the practice field Wednesday for the first time since Sunday’s win over the Cardinals, as they prepare for Super Bowl 50.

Well, most of them were back, anyway.

Defensive end Jared Allen, who reluctantly sat out the conference championship game after breaking a bone in his foot, was practicing. Allen has never been to a Super Bowl and doesn’t want to miss what might be his last chance.

Safety Roman Harper, who left the game early after hurting his eye, was also on the field.

Running backs Jonathan Stewart and Mike Tolbert were among those on the sideline. But neither is expected to miss the game. Stewart played well against Arizona despite a foot injury and Tolbert had his knee checked Monday.

Linebacker Tom Davis remains adamant he’ll play with a surgically repaired broken arm but didn’t practice Wednesday.

It’s the Super Bowl. Face it. Any player, short of having the last rights read over them, is going to insist he’s fine; That it’s just a flesh wound. Even if it isn’t.
