Which young corner back will have a more successful career for the Patriots? There really isn't much evidence at this point to answer this so it will be more of a guess. I realize that McCourty hasn't played a down in the NFL but he was our first round pick this year at pick 27 and was a productive college player. Darius Butler was chosen 41 in the 2nd round of the 2009 draft. Butler showed last season that he has potential to be a good corner in the NFL. I also expect McCourty to have a decent rookie season, but who will be more successful for the Patriots in the upcoming years? I think that McCourty will be a productive player on special teams at first and develop into a good corner within the next couple years. I also believe that Butler will be a starter soon to come and immediately be productive.
