Still, there is intrigue.
"There is a possibility," Flores said Friday after practice via the Dolphins' team website. "It will be a tough thing to do, obviously. He wants to play. Kid loves football. Hopefully we can get him up to speed then maybe, but it's a tough thing to do. No promises on that. He knows that. He's been in our meetings. He's asking questions. He's very eager to get in there, whether it's scout team or defensively. With that type of attitude he'll be in there sooner than later."
It wasn't exactly a friendly parting of the ways, as Charlton tweeted "free me" before his release and Cowboys owner Jerry Jones certainly didn't have the most glowing of descriptions for the defensive lineman.
"You've got to be absolutely be eating raw meat to be a defensive lineman, in my mind," Jones said via the Fort Worth Star-Telegram. "For whatever the reason that area of Taco, and it had as much to do with his own disappointment, his own feeling that he can do better. I've seen him do a rep in practice, and when he didn't get there, he just wilted. It just looked like it impacted everything that he was going to do for the rest of the practice. You can say, 'Well, I can correct that if you're a coach.' But on the other hand, you got to get it done."
Whether Charlton can get it done or not with the Dolphins is a quandary that will play out beyond Sunday. But whether or not Charlton lines up against his former team inside of a week since his departure is intriguing, indeed.
