Along with Greenlee, there were several other standout performances highlighted by Fork Union (Va.) Fork Union Military Academy's Christian Hackenberg and Harbor City (Calif.) Narbonne's Troy Williams.
Hackenberg had a strong showing in what was his first camp performance of the year.
"Christian lived up to all the hype for sure," Elite 11 QB coach Matt James said. "He has great size and arm strength and can really get the ball down the field. He can throw the digs, skinny posts and comebacks, where you can see his arm strength and his ability to drive the ball deep down the field.
"He can really make every throw you're looking for in a college quarterback and was my top guy for the day. We've seen his film but this was the first time we've seen him in person with live bullets coming at him and he was very impressive."
Williams attended the NIKE Camp at Cerritos but looked a lot more comfortable in Vegas. He has a quick, effortless release, throws with touch and can spin the football as well as anyone you'll see. He has plenty of arm strength, throws well on the run and looked great running the two minute drill at the end of the camp.
"Troy is great on film and he's a gamer for sure," James said. "He had a solid all around day but really stepped it up in the two minute drill when the pressure was on. It was good to see him step it up at the end there when it mattered most."
*Shane Cockerille, Baltimore (Md.) Gilman- Strong armed lefty had one of the most powerful arms in the camp. The Maryland commit has a strong frame as well and is an intriguing player with a nice upside.
*Danny Etling, Terre Haute (Ind.) South Vigo- Attended Elite 11 camps at Dallas and Columbus and looked good in Vegas. Has nice size and pocket awareness and looks very comfortable playing under center.
*Jihad Vercher, Los Angeles (Calif.) Salesian- Vercher never disappoints and he was strong again Saturday. A pure thrower who can really spin the football and has a very powerful downfield arm.
*Davis Webb, Prosper (Texas)- Big kid with a nice downfield arm. Showed good accuracy and was easily among the top quarterbacks of the day.
*Chris Laviano, Hicksville (N.Y.) Holy Trinity- Showed a lot of polish and is a true field general. Has solid physical tools and knows where to go with the football.
*Brandon Cox, Pasadena (Calif.)- Had a much stronger showing this weekend than he did at the Cerritos NIKE Camp. Still needs more consistency but when he sets himself and throws in rhythm, he can really deliver a nice ball.
*Kelly Hilinski, Sherman Oaks (Calif.) Notre Dame- After earning NIKE Camp MVP honors in Oregon last week, Hilinski had another strong showing. He was very accurate, throws a tight ball and has plenty of arm strength.
*Brandon Dawkins (2014), Westlake Village (Calif.) Oaks Christian- Dawkins was moved up to the top group, despite being an underclassmen, and impressed. He has great size and arm strength and as he continues to refine his mechanics, he has a chance to be a very special player.
*Conner Manning, El Toro (Calif.)- QB MVP at the NIKE Camp in Cerritos and looked solid on Saturday. Throws with touch and is very accurate.
*Isaac Dotson, Newport (Wash.)- Dotson might be more of an athlete than a pure quarterback but is definitely an intriguing player. Good sized kid who moves around very well and made some nice throws.
