SANTA CLARA – What you see is not necessarily what you get once training camp comes to an end.
Yes, undrafted rookie guard/center Erik Magnuson was seen on video posted on the 49ers official website working with the 49ers’ first-team offensive line. But, according to Kyle Shanahan, it was not exactly the 49ers’ first-team offensive line.
The 49ers practiced this week as if they were getting ready for a regular-season game. During the season, the second-team offense does not take the field together to run plays. The starting unit might feature a backup at a position or two to give starters a break.
