The spring evaluation period began yesterday and Stanford has already been in to see the 6-foot-5 prospect, but Notre Dame, Ohio State, Rutgers, Boston College, Penn State and Northwestern are currently in the lead.
"In the next two weeks, we'll have somewhere between 15 or 20 schools in to see him," Portella said. "He has his five or six now but it could change."
Notre Dame is in the best position for Nelson but recently added its second offensive line commit. Nelson recently visited Rutgers for a pair of practices and has the home-state school among his top schools.
"He had a great visit over at Rutgers," Portella said. "He likes the place a lot. He certainly has a lot of good things to say about coach Flood. Rutgers is in his top five right now and he's very comfortable with the people there."
Nelson and Red Bank Catholic had a strong relationship with former assistant Robb Smith, who left for the Tampa Bay Buccaneers, but remain comfortable with head coach Kyle Flood and his staff.
"We have a good one," Portella said. "We miss coach Smith, but we know [offensive line coach Damian Wroblewski] and coach Flood. They've all been great. We're not concerned about Rutgers. It's a great staff. Coach Flood is great. I've known him back since he was at Delaware and he was a first-class guy. We're always happy if we can send a kid to Rutgers as the in-state school."
Nelson has legitimate interest in multiple West Coast programs and leaving home will not be an issue.
"Like all kids, of course he's close to his parents but he's not concerned about distance at all," Portella said. "If the right school is in California, then that's where he's going to go. He hasn't balked at any possibility."
The 6-foot-5, 295-pound Nelson is the No. 8 overall prospect at his position in the class of 2014 and checks in as one of the top five players in the state. He has more than 30 verbal scholarship offers.
"The reason he's a good kid to go after is, No. 1, he's a great football player," Portella said. "He's got great technique. He plays with an edge. A lot of offensive linemen with his size don't play with his ability. He's nasty in a good way. He's a good academic kid and obviously schools like Stanford aren't going to offer you if you're not that kind of kid. No. 3, he's a good person. He's a good leader and a good kid. This whole process hasn't changed him negatively at all."
