"Recruiting has been going good for me because I have a lot of offers," said Zwinak. "I now have offers from Maryland, Virginia Tech, Penn State, Pittsburgh, Michigan, Syracuse, Wake Forest, North Carolina State, West Virginia, Rutgers, California, and Stanford."
Checking in at 6-foot-1 and 227 pounds, Zwinak dominated the competition during his junior campaign.
He carried the ball 133 times for 1,447 yards and 19 touchdowns as a junior. On defense he totaled 53 tackles, 11 tackles for loss, sacked the quarterback five times, had three interceptions and forced three fumbles. However, he indicated he is being recruited strictly as a fullback.
He was named Player of the Year by both the Frederick News Post and the Gazette and also earned first-team All-Area, All-Conference and All-State honors at running back. He was named second-team All-Met at running back as well.
"Zwinak runs and blocks like a bull in a china shop, he destroys whatever is in his path," said Scout.com Recruiting Analyst Bob Lichtenfels. "He hits the hole quick and is very light on his feet for such a big back, he cuts just as well as most small backs. Once he hits the seam he has very good breakaway speed and switches the ball to the outside arm.
"He is a devastating lead blocker... I would like to see him run a little lower through the the line."
"Zach is an outstanding college football prospect," said Linganore head coach Rick Conner. "He's big, fast, powerful and he loves the game. Zach started on both sides of the ball the last two years as a running back and linebacker, a tribute to his natural ability.
"What separates Zach from others is his athletic agility combined with his size and speed. He's very versatile and can fill many roles. Zach made a great jump in performance from last year to his junior year. He put himself at the top of the list in Maryland and has become a national recruit.
"He can dominate a game on either offense or defense. Offensively, he can wear you down with his power or he can score on one play with his break-away speed from anywhere on the field. Zach is very familiar with college athletics as both his parents were scholarship athletes."
"Colleges like how I'm physical, and they say I'm a good athlete," said Zwinak. "I probably need to work on my agility and overall speed. I'm fast, but I can always get faster."
Zwinak has already visited a few schools.
"I visited Maryland a while ago and Penn State with Rob [Havenstein]," he said. "I've also been to Rutgers and Virginia Tech."
Zwinak has ties to a couple of programs. His father played footaball at Virginia Tech and his mother ran track at North Carolina. Will those ties play a role in his decision?
"My dad is leaving it up to me," said Zwinak. "When I first got into football I followed Virginia Tech because of him playing there, but I follow a lot of teams.
"My mom went to North Carolina so I'm also a UNC fan... they haven't offered yet. The coach came in the other day and saw my tape, but I don't know if they are going to offer or not."
One of his recent offers arrived from NC State.
"I have family down in South Carolina, so NC State is close to them," said Zwinak. "They are in the ACC so that's a plus, and they have a good team every year. I haven't visited them yet though.
"The coach came in and watched my film. He told coach Conner he was going to offer me and then the offer came. They've offered Rob too."
With several options on the table, Zwinak is in no rush to make a decision.
"I wanted to wait a while, but it will probably be in the fall sometime," he said. "I'm not really sure yet what will be the deciding factor. When we sit down and start making a list, the big factor will come out then. Right now I'm wide open and not in a hurry."
