Beller: With Mike Wallace down in Miami, Antonio Brown ascends to the top of the depth chart in Pittsburgh. By season's end, he'll be worthy of topping a fantasy depth chart at receiver, as well. As I pointed out in my target analysis, Wallace received 25.1 percent of the Steelers' targets last year, and nearly 30 percent of their red zone pass attempts. Not only will Brown siphon off plenty of those, Emmanuel Sanders does not present the same threat as a No. 2 that he did behind Wallace. Brown should easily fall somewhere in the 1,000-1,200-yard range with eight to 10 scores.
