But Greer was a big contributor to the Cavs' CIF D-III State Championship season last fall.
While he had to wait for his first offer longer than he had hoped, one finally came, and it was a big one.
"Michigan offered me over spring break," said Greer. "It was pretty exciting. I was really excited about it because Michigan is a big school."
Greer said that some Pac-10 schools could be next.
"Oregon is talking to me about offering, they just want to come watch me in spring practice but their linebackers coach really likes me," said Greer. "And Washington, Arizona and Arizona State could be next."
Greer said he's also interested in the Los Angeles schools.
"I went to USC's Junior Day, but I haven't really heard anything from them. I'm going to the Rising Stars Camp though. And UCLA, their d-line coach (Todd Howard), said I'm on their board and they're going to come watch me in the spring."
Greer said he doesn't mind waiting on more offers, since he's not planning an early decision.
"I'm not in a rush at all," said Greer. "I won't decide until the beginning of the season or the middle of the season."
Greer said all of his attention is coming outside.
"Schools are recruiting me as an outside linebacker which is cool because that's what I want to play," said Greer.
Greer said he had five schools that are standing out in the early going.
"My top five right now is Michigan of course, they're my top school, Oregon, Washington, Arizona and Cal."
Academically, Greer has a 2.6 and will take the SAT on May 1st.
Last fall, he had 140 tackles and 11.5 sacks for the Cavs' 15-0 squad.
