Listen, I'm a BIG Barrett fan. I have picked him in every year in fantasy since his rookie year, later in the draft, and he helped me win last year. But as a fantasy player I already know Keegan would contribute more as a rookie than Barret did even last year when he finally put up more consistent "numbers" but percentages were still all over the board.
Murrays efficiency is still too damn tough to pass up on. Dude plays like a veteran.
