I would say Logan and Taylor. By the end of the season, Alfred Blue may be a household name in SEC country.
Logan didn't come out of nowhere. Unless you are referring to the average fan. When he came in he was seen as a little bit of a work in progress but there was serious talent and potential. Even the 5 star guys don't work out sometimes but you coach em up and hope they turn into a player and contributor. Safe to say Logan has taken that step this year.
By average fan I just mean those that don't follow recruiting or the team other than during the season. Didn't mean it in a snobbish way.
FWIW I have to say Stamp and or Lee. Stamp is a hammer. We have talked Lee and the QB situation to death but I think Lee has to be the most underrated as far as him exceeding most if not all people's expectations. Within his teams system and offensive philosophy he is playing the QB position as well or better than anyone in the SEC.
He popped into my mind too. There are many though. None will be under-rated if LSU takes care of business on 11/5. :geauxtige
I think Brooks is a bit underrated. Dude flies all over the place on ST. I do agree with the ones of you that say that Logan is most underrated, though.
Logan made a showing in the Spring game........... Look at this Mock Draft for 2012, look at whos #10........ WalterFootball.com: 2012 NFL Mock Draft
