(Undated) -- Another top quarterback is entering the transfer portal. USC QB Jaxson Dart entered the portal on Monday, becoming the latest collegiate star to possibly be on the move before next season. Dart split time under center with Kedon Slovis last season for the Trojans. He threw for 1,353 yards, nine touchdowns and five picks over six games of action. The decision comes after Caleb Williams entered the portal last week and could possibly reunite with Lincoln Riley at USC. ESPN reports the Trojans are among the top schools under consideration for the Oklahoma QB.
