That is terrible news. Way too young and a wakeup call to someone my age who was at school the same time and lived in the same dorm at least one of Marc's years at Illinois. I had a friend in that dorm who was handicapped and things didn't always come easy, but Marc always was so nice, would eat meals together and ask about her classes and always lifted her spirits up, just the most sincere, thoughtful person.
I always heard Marc played really well in practice at Illinois and it never translated to the games for whatever reason. He was a heck of a high school player at Aurora Christian and part of a smaller Illini recruiting class I think with Robert Bennett because of the unfair/BS fallout from Bruce Pearl and Iowa.
I did not know Marc had cancer or had gone on to such a great coaching career. His dad is a coaching legend in Aurora whose school gym is named after. If there's anything to help through news like this, I can't think of a family more at peace that Marc has made it home now.
