I am pretty sure did nothing till their redshirt soph year . Stith was forced into action as a frosh but redshirted his soph year the point is that these guys rarely impact till they are in the second mostly 3rd year . Wilson played his true freshman year but did not do a lot but maybe coaches felt he wouldn't be here for 4 years so why not play him . Wilson was a great athlete but his vision at the RB spot lacked he was not a natural runner like Williams .
