Many NFL players about to hit free agency dream of being the subject of a bidding war between teams. Those guys agree to deals in the first few hours of the negotiating period. By the time we get to Day 3 of the new league year (and Day 5 of the free agent window that opens with the start of the negotiation period), there aren't many of those bidding wars happening. Players who might have expected to pick between three or four teams might just be hoping the right one sends them an offer. The market flips from players to teams quickly.
