In redraft leagues he is eating up a roster spot and the earliest conceivable time that he will play this year is week 10. With how badly AJ Smith and the Chargers screwed him, it's virtually assured that he is going to report for the minimum amount of time necessary to get his year of eligibility so that he can become a free agent next year and play for whoever offers him the biggest contract.
This is almost certainly not true. He has accrued enough years to be an unrestricted free agent in any year other than the uncapped year. So many players got screwed by the extra year of restricted free agency this year there is no chance that it will remain in the next collective bargaining agreement. He'll be a free agent when football resumes, so there is no reason for him to report, other than to collect a couple hundred thousand dollars. I don't think we see him this year (unless he gets traded, which is still possible).
