I expect the 49ers to make a number of moves. DE, WR and CB come to mind. OLine would be great but no one trades quality OLine players. I am not sure if they will make a big trade though. They need to value draft capital a little more than they used to because once they sign Purdy to an extension they will not be able to keep absolutely every star player like they have in the past. I am curious to see what they do. I think if an absolute stud becomes available like a Garrett or Parsons or Kupp they will jump at it. Otherwise I expect they will make moves around the edges.
Have to remember the 49ers will be getting back 2 all pros in CMC and Hufunga and a pro bowl caliber player in Greenlaw sometime in the second half.
