With the way NFL officials are allowing holding expect to see more teams using 4 WR formations. Its nice to be ahead of the curve for once. Plus we have 4 good WR's to take full advantage of this. Its also means Allen has the field vision to find the open WR, you will probably never see Lamar in a 4 WR set. Lamars WR's hate him and his TE's love him, plus his field vision is horrid.
