Looking back on three things discussed here before the San Francisco 49ers' 15-13 exhibition victory Friday night against the Kansas City Chiefs at Arrowhead Stadium:1. QB comparison. There wasn't much to compare because these teams took vastly different approaches to the game. The 49ers removed quarterback Colin Kaepernick after one series. The drive started with Frank Gore breaking a 52-yard run. It ended with a field goal after Kaepernick overshot receiver Chad Hall for what should have been a touchdown.
