Matt Maiocco of CSNBayArea.com did a player-by-player breakdown of the 49ers’ performance against the Colts in each teams’ preseason opener on Sunday, offering up this analysis of the efforts of offensive lineman Alex Boone:

    Entered at beginning of second half at left tackle and played the rest of the way, 31 snaps. He was called for a holding penalty, but his feet looked much better than last summer. He did a very good job in the second half of handling defensive end Ervin Baldwin one-on-one.
