Not by what Greenberry has done on the field despite the constant phone calls from recruiters and reporters, and with questions swirling about the stability of his recruitment.
For the record, the 6-foot-2, 195-pound Greenberry did not visit USC this weekend, and when asked if he was still solid to Notre Dame and planned on signing a national letter of intent, he unequivocally said, "of course."
He was visited by Irish assist Mike Denbrock on Wednesday, and he is expecting another visit by a member of the Notre Dame staff before the holidays.
As for his conversation with Denbrock last week, Greenberry categorized it as normal. "He just talked to me. That is it," Greenberry said. "There's nothing new with them. It's the same. We just talk."
Greenberry didn't give a reason why he canceled his trip to USC, but didn't rule out the possibility of making one in the future.
"I don't know yet," he said when asked about a future trip to USC.
Greenberry already made official visits to Notre Dame and Arizona State, and he maintained for a long time he was going to get in all five official visits just to experience them, but he was solid with the Irish.
For now, though, his focus remains on a torrid senior season in which his statistics go beyond gaudy. Defenses are trying to cover him with double and triple teams, but to no avail.
Greenberry set goals of amassing 2,000 yards and 20 receiving touchdowns, and is actually going to teach them.
He will enter this week's state semifinal playoff game with 92 catches for 1,890 yards and 28 touchdowns after another big performance in Friday's 35-0 win against Coalinga (Calif.) High. He caught nine passes for 144 yards and a touchdown.
"It's been a blessing," he said. "Teams have tried cover-2 on me and combine it with a cornerback in my face or three or four people on me. I just beat the jam and am going up and getting the pass."
Washington Union next faces Wasco (Calif.) High in the CIF Central Section playoffs Friday, and Greenberry is looking to continue his momentous season.
"It's an experience like I knew it would be," Greenberry said. "I had a goal and I've reached my goals, and my goals were pretty high. I was just trying to get close."
