The Vikings SEEM to be in a good position to go after RWilliams, but people seem to be forgetting the two reasons they won't:
1) They already have a guy that's been suspended for a year, and wouldn't want 2 on the roster that could be gone for a year each (not saying OSmith would necessarily come back, but even just that having happened to Minn recently makes this unlikely, IMO).
2) The team owner is very much about a new cleaned up code of conduct. Why would they bring in an admitted pot-smoker when they are trying to IMPROVE team image. People may point to KRob, but he was brought in on a zero-tolerance type 1 year deal, and they wouldn't be able to get Ricky on the same type of deal - you can't trade Cpep or high picks away for a guy that you are gonna put a zero-tolerance policy on.
Minn SEEMS like a good fit, but I doubt it. Now if Linehan somehows ends up back in Minn, maybe then he convinces the owner to take a chance on Ricky, but the trade would not involve Culpepper then either.
