Uh, if there is a link, I'd also have to assume its the link formed by two people with deep seeded hatred for each others' personal beliefs.
LaPointe (aka GrahamKracker) was as anti-nickname as anyone ever. Peltier may not have been as vocal as LaPointe but he was for the nickname. I doubt they'd be friends, unless LaPointe is all talk.
I mean, it would be like George W. Bush and Nancy Pelosi saying they are close friends and meet regularly to discuss the latest book in Oprah's Book Club.
Of course, undsportsfan, there is one difference: LaPointe quit UND. Peltier resigned his post. He did not leave UND.
