Pretty simple economics with Kearse: He and his agent figured he was a #2 WR and should be paid #2 money. He explores the market and discovers that the market is willing to pay #3 or #4 WR money. So he returns to the Hawks who sweetened their deal a little and now both sides appear happy.

Not too difficult to figure out. Most players/agents shoot for the moon as players only get a couple shots at big money. But the league isn't spending big on WRs, RBs, and OL. QB's and Defense is where the cash is at right now.
