Two of the quarterbacks San Francisco 49ers coach Jim Harbaugh has played close attention to this offseason are Virginia Tech's Logan Thomas and Eastern Illinois' Jimmy Garoppolo.The 49ers may be looking for a quarterback to develop in the mid-rounds. While Garoppolo could go in the second round, Thomas could be available late in the third round. ESPN analyst Jon Gruden did not work with either quarterback during his famous Gruden QB camp.
