SANTA CLARA -- The offseason gives NFL teams -- especially ones with new coaching staffs -- a chance to experiment with players lining up in new spots, and the 49ers seem to be doing quite a bit of that in their OTA sessions. The following is a list of players who are in spots they did not play last season. Some may be temporary moves, others, such as tight end Bruce Miller, appear to be permanent.
Alex Balducci*, C. The 49ers are seeing if the former Oregon nose tackle can play center. Balducci was the team's third-string center in last week's OTA session.
