The San Francisco 49ers exchanged a 2012 seventh-round pick for 2013 fourth- and 2014 seventh-round picks Monday. That sounds like a pretty good deal and it's typical of the 49ers maximizing value. No one went into the 2013 draft with more picks than the 49ers possessed, and already San Francisco could have as many as 13 selections for next year.The most recent accounting looks like this: 49ers outside linebacker Cam Johnson, a 2012 seventh-round pick coming off an impressive preseason, goes to the Indianapolis Colts for what is reportedly a 2014 seventh-round pick.
