Greenlee, who arrived in Las Vegas looking stronger since the season, used the opportunity to come out and show off his big arm, something he isn't always able to do in the Trojans' run-heavy offense.
"It feels great to have no rush and wing the ball, have all the routes and schemes and see the coverage and just be able to throw the ball," he said.
The event marked one of the first times since season that West Coast athletes were able to play in this capacity, and the quarterback enjoyed getting back on the field.
"It's great to come out here and compete, come out here with the guys, have great competition with the best guys out here. It's been a while since we played football so just getting out here is great," he said.
"I'm talking with the receiver coach at Tulane, Keith Williams. He wants me to come down there for their camp in June, and I'll be getting down to that," he said.
He also recently took an unofficial visit to see the Bulldogs and really enjoyed his time on campus.
"I got to spend time at their spring practice and talk with some of the coaches, including their new offensive coordinator, Dave Schram. We spoke about what they are trying to do with their offense. He definitely tied in a lot of things from Lincoln. My sophomore year, we ran a lot of shotgun and they are trying to do that now. He talked to me about that after he saw it on my film and he said I fit in well. He showed me some other schemes and I really think I could fit in there," Greenlee said.
Greenlee, who lists arm strength, touch, accuracy, and footwork as his player strengths, has plans to return to campus again soon.
"They asked me to come back and I'll definitely be going back there for both their camp and another unofficial visit. I just felt comfortable. A lot of receivers that I have worked with have gone to school there. The coaches are really nice and they have a good program," he said.
"I emailed their coach and he said he would be coming down for spring ball. I'm really looking forward to talking with him," he said.
The Lincoln Trojans will be heavy into spring ball throughout May and Greenlee is looking forward to making an impression to all coaches, as proximity is not an issue for him.
"I want to be comfortable, somewhere with great coaches where I can fit in with their offense and what they are trying to do. I'll go wherever is best for me, whether it's a local school or across the country. I have no problem with that," he said.
As he continues his off-season training, the 6'2", 195 lb. Greenlee is hoping to put on a few more pounds and work on certain aspects of his game.
"I'm hoping to hit the 200 lb. mark by senior season, and to get another inch or two before I leave high school. I've really been working on improving on my completion percentage, just completing every ball. I'm also studying pre-snap reads, post-snap reads, just understanding all of the coverages so I can lead my high school team come season," he said.
