I remember when an unheralded 2-star from Alabama came onto campus for fall practice, took his position from Day 1 and just refused to give it up to anyone - veterans, other noobs - anyone. Captain Munnerlyn went on to have a 10-year pro career and still has a number of Carolina Panthers records. So who in your mind could swoop in out of nowhere (I think Captain only had three offers out of high school?) and make his mark this year?
