Diamond, a 6-foot-6, 300-pounder from Simeon Vocational High (Chicago), said he is talking regularly with Irish coach Brian Kelly and assistant coach Chuck Martin, and he likes the direction of the program.
"Even though they started off real slow, just like last year with a young team," Diamond said. "It's kind of hard starting out with a young team, but they're improved. Notre Dame is catching my eye."
Diamond is still planning an unofficial visit for Oct. 22, but a trip to Notre Dame is a possibility. "It's either going to be that game, or Michigan State (against Wisconsin)," Diamond said. "I'm not sure."
Diamond made a visit to Notre Dame in the spring and came away impressed, and the school always stayed on his mind.
"I just thought it was a great school with a lot of potential," he said. "I can't wait to get back down there. If I can't get there for a game, I'll probably go after the season. Notre Dame is a good school. Obviously, I like Notre Dame and they're still recruiting me. Coach Kelly is a great guy. Coach Martin, I talk to him, too."
The discussions with Kelly and Martin range from talking about everyday events to how Diamond would fit into Notre Dame's offense.
"They say they just need some skilled tackles, tackles that are athletic," Diamond said. "With the spread they're running now, they have to have athletic guards and centers and every spot on the line. They say I'd be a good fit there."
Despite Diamond's affinity for Notre Dame, he does not have any leaders and is yet to narrow a lengthy list that includes offers from most of the Big Ten schools, a handful of SEC schools and plenty of others.
So, where does Notre Dame rank on his list?
"They're just like every school, at the mid-level," Diamond said. "I haven't made any point-blank effort (directed) at any school right now. I'm going to wait until after the season for all of that.
"I'm still talking to every school. I'm going to keep myself open right now."
