Brown is a gifted kick returner, no question, but he needs lots of work at WR. Watch him next game, he is lazy running routes, sometimes only jogs. This is especially true if he's not the primary receiver. Also he's very slight, came in only weighing 160 or so, probably in the 150s now. He'll benefit greatly from S&C, gain weight and increase his hand strength, something he greatly needs. I hope he stays and works to get better.
Levis has mentioned he and the WR(s) aren't always on the same page. Wonder who he's talking about?
