I ... don't ... know. It may simply have meant that no one was willing to pay what Tennessee was asking.
We can't assume no players were available because they weren't traded because there are several reasons why a trade doesn't develop. I would have called the Titans and offered them a third-rounder. If they wanted more, I would have offered them a conditional pick the next year (perhaps up to another third depending on playing time/yardage). I see a need and I want to address it, within reason, of course. For all we know, though, maybe Dallas made the Titans such an offer and they wanted even more. We simply don't know if Henry was available or wasn't; only that he wasn't traded.
Your assumption seems to be if they weren't traded, they weren't available. Every year, there are trades that fall through or players who are kept because no one offered enough. Last year, we tried to trade for Brandin Cooks before the trade deadline, the deal fell through and Cooks remained with the Texans.
My problem isn't that we may have been unable to trade for Henry but rather that Jones indicated that he was satisfied with what we have and wasn't interested in looking. I don't think you improve the team with that outlook. Now, there did seem to be some indication that we may have checked into the price for acquiring the Chicago cornerback.
