Havenstein was named first-team All-Conference, All-Area, All-Met and All State as a junior.
His off-season has been going "pretty well. I'm lifting, running, trying to get in shape and everything," he said.
He is focusing on a few things in particular, but he is always working on everything. "Right now, with my foot speed, [I am] trying to get more explosive coming out of my stance."
Havenstein has been to visit the University of Maryland, and recently went a month or two ago for a practice.
"I really love Maryland; it's my home state," he said. "I really liked the way practice was run; it was really high energy."
However, with no set list of schools, Havenstein has not put too much thought into one aspect of a prospective college.
"I haven't really put much thought into [football style, but] I've always been a run blocker."
Linganore head coach Rick Conner talked about Havenstein's value and how most of the team's rushing yards came behind him on the offensive line.
"You name it, Rob can do it," Conner said. "Simply put, Robby is a coach's dream."
