Over the last three weeks, it's been a tale of two halves - literally - for Nelson. Against Oakland and in the first half against New England, Nelson was virtually unstoppable, hauling in 16 receptions for 167 yards and a game-winning touchdown. That's a very stellar six-quarter stat line.
Nelson has played six quarters since then, as well - the second half of the New England game, as well as yesterday's game against Cincinnati. In those six quarters, Nelson has two receptions for 18 yards.
Why the sudden drop in productivity? Bill Belichick noticed that Nelson was Ryan Fitzpatrick's highly productive safety valve and removed him from the equation; Nelson didn't have a second-half catch against the Pats. Cincinnati took him away, too. Until other Bills receivers - Donald Jones chief among them - start making more plays, expect opponents to keep plugging up passing lanes over the middle and taking Nelson out of the equation.
