Weekend mail call:Jackie from Euclid, Ohio, wants to know: Who is the best receiver the San Francisco 49ers could get in the draft?Bill Williamson: I think they can get up to the Nos. 10-12 range in the first round. That could put them in position to draft Mike Evans from Texas A&M. However, this is a deep class and the 49ers, who have the 30th pick in the first round, may find it best to stay in the back end of the round and see who falls to them.
