Through four weeks of the college football season, plenty of transfers have already made a big impact on their new teams.
A number of highly talented players picked new schools this past offseason, including quarterback Caleb Williams and receiver Jordan Addison, who both picked USC. Williams wasn't the only quarterback to switch schools, as former USC signal-caller Jaxson Dart left for Ole Miss, Oklahoma quarterback Spencer Rattler went to South Carolina and Texas quarterback Casey Thompson picked Nebraska as his new school.
Those new additions are among the many players who have already made marks at their new schools. With enough of a sample size a month into the season to give us a good grasp of who is standing out, these are the transfers at each position who have made the biggest impact this season.
QB: Caleb Williams, USC
Williams has reenergized the USC offense and helped the sixth-ranked Trojans to a 4-0 start, their third since 2011. He has 1,054 passing yards and nine touchdowns with no interceptions. He also has 100 rushing yards and two rushing touchdowns.
Amid a wild coaching carousel and transfer portal cycle last year, Williams followed coach Lincoln Riley to USC from Oklahoma and turned the Trojans into College Football Playoff contenders.
Other notable quarterbacks: Michael Penix Jr., Washington; Adrian Martinez, Kansas State; Hendon Hooker, Tennessee; Will Levis, Kentucky; Dillon Gabriel, Oklahoma
