If I were Detroit I would hold out for as much as Jerry is going to give up. After watching him fold to the Titans when the ONLY guy he was bidding against was himself and it was clear that the Titans weren't going to keep him around Jerry made them an offer they far above what his original intentions were and they laughed all the way to the draft.
Now, don't get me wrong, if this whole Adam Jones thing works out we got a steal, BUT the fact that Jerry wasn't in a bidding war with another team and buckled shows that he is working, almost, from a desperation stand point.
The Lions may as well let Jerry stew on this on this one for a bit until he just explodes from the anticipation. It's no secret that Williams has been Jones' target since the very first day of the off-season. Now that the Lions have made it known that Williams might be available for a "real" deal, then all they have to do is sit and wait until Jerry, once again, folds.
The only other concern is the fact that the Eagles have two 1st rounders next year and are in desperate need of WR help. It's not typical of the Eagles to get loose and gamble with draft picks, but the leverage that they have with those picks and the fact that a division that they finished last in, the previous season, hasn't gotten any weaker may indeed prompt them to dazzle the Lions with an offer they can't refuse and Jerry can't match.
Interesting to say the least.
