One example was just how much the San Francisco 49ers have invested in their offensive line:
San Francisco and Indianapolis have used the most first- and second-round picks for offensive linemen over the last five drafts, each with four. But the 49ers used three first-rounders on the position during that time, while the Colts used three second-rounders. The 49ers are the only team in the league to use more than two first-round picks on offensive linemen in the last five drafts. Tennessee and San Diego have used no first- or second-round picks on offensive linemen over the last five drafts. They are the only teams to have used none.
