Great article predicting 49ers will have to trade up in first round to get replacement for Justin Smith. No way they can afford to sign more than 5 or 6 rookies and good pickins up high.

"There is no way that the 49ers can keep more than five or six new draft picks with the way the team is structured right now. Expect GM Trent Baalke to either trade up or trade out for picks in the future. The talk around the league is that the 49ers would like to get a defensive lineman who can eventually step in for veteran Justin Smith."
