Former Oakland Raiders defensive lineman Richard Seymour is arguably the best NFL free agent still on the market, but he doesn't need to play football again. As one of the highest paid players of his generation, Seymour can afford to be choosy. Speaking on Sirius XM NFL Radio on Tuesday, Seymour said he had no regrets about his career thus far. And he sounded ready to retire if he didn't get the right offer, saying "so be it" if it's time to move on to another chapter. Seymour pointed out that he could have signed with a team if he wanted to by now, but the offers haven't been right and Seymour probably isn't in a hurry to report to training camp on time unless he gets the nice deal.
