Tebow, the Jets' big offseason acquisition, has spent the past five days making adjustments to his throwing motion under the tutelage of Tom House, a former major league pitcher now working as a volunteer pitching coach at USC.
The workouts have been conducted at USC's gated-off Howard Jones Field, and media have not been allowed to watch per Tebow's request, House said.
Tebow had his last mechanics session with House on Friday and plans to fly back to New York this weekend. The Jets begin training camp on Thursday in Cortland, N.Y.
The typical quarterback's schedule is a weeklong program at the Rod Dedeaux Research and Baseball Institute on the USC campus, where 3D video analysis is used in coordination with traditional drills to break down individual motions to a thousand frames per second and discover small inconsistencies or errors.
House said Friday he believes Tebow benefited from the week's worth of workouts.
"I think he's getting better, but the proof is in the pudding," House said. "Being out here at USC is different than being with the New York Jets."
Tebow and USC coach Lane Kiffin share the same agent, Jimmy Sexton of L.A.-based Creative Artists Agency. Sexton originally arranged for Tebow to work out on the school's campus last month, and the controversial third-year quarterback began throwing on his own then and using the university's weight room.
A Trojans' program source told ESPNLosAngeles.com that Tebow has used USC receiver Marqise Lee as one of his targets during throwing sessions. Lee is a talented sophomore expected to be a top pick in the 2014 NFL draft.
Current Jets receiver Patrick Turner, who also played at USC, has caught passes from Tebow, as well.
