Dude (S.C.) is strong - what I mean is he's psychologically and physically very strong - U .S. Marine corps type of strong because a lot of people after the Iowa State debacle would have crumbled psychologically and never regained their former athletic level but he's gone on to a new different level despite all the negativity surrounding his transfer and that demonstrates a stoicism and strength of character which portends future greatness.
Other individuals might have just faded into the woodwork (and mediocrity) and kept their head down but Seth has had the courage to continue fighting and he's now showing a super impressive level in Division 3 and that shows a strength of character rare for someone facing all these challenges.
One has to respect that. Dude is strong.
