COLUMBIA, Mo. (AP) — As time was expiring in Missouri's duel with Purdue, Tucker McCann drilled a winning 25-yard field goal to move the Tigers to their first 3-0 start since 2015. He probably wouldn't have had the chance without Drew Lock. The senior quarterback has led the Tigers to at least 40 points in each game this season, including the 40-37 shootout win over the Boilermakers on Saturday.
