"I went to Penn State last weekend (spring game), and I was to Ohio State for its spring game," the 5-foot-11 170-pound Dotson said. "I'm trying to get to Michigan in May.
"It's pretty much those three. I hope to decide in the next month or so."
Dotson was born in northern New Jersey, but he moved to Pennsylvania when he was 7-years-old. He spent his first two years of high school at Nazereth (Pa.) High before transferring to Peddie, a boarding school.
In talking to the Penn State staff, representing the Keystone State is a big part of his recruitment.
"Basically, it's staying home," Dotson said. "I'm building relationships with a lot of the coaches. I have a great relationship with (receivers) coach (Josh) Gattis, and basically staying home is the biggest thing. It's close to home. I know a lot of people that go there, so that's big for me."
Ohio State is telling Dotson it needs him to come in early and impact the receivers group.
"I have a great relationship with (receivers) coach (Zach) Smith," Dotson said. "Coach (Urban) Meyer knows how to prepare people for the next level on and off the field, so I am really looking forward to that."
Dotson also has a connection to Ohio State quarterback Dwayne Haskins, who grew up in New Jersey but moved to Maryland during high school.
"I know Dwayne is going to be the quarterback in a couple of years," Dotson said. "I know he has a great arm. I've thrown with him a couple of times, so that would be cool for me."
Getting to visit campus a few weeks ago gave Dotson a close look at the facilities, and he learned plenty about the inner workings of the program.
"It was pretty cool because I got to spend a lot of time with the coaches," Dotson said. "I got to sit in coach Smith's office and talk to my family, and he showed me routes and teaching points."
Although Michigan assistant coach Chris Partridge, a former coach at Paramus (N.J.) Catholic, did not coach Dotson in high school, the ties to north Jersey run strong.
"I have a great relationship with him," Dotson said. "They like to throw the ball, a lot of play-action. If that's what they need, then I'll fit."
