Sams is a quarterback and different than Collin Klein.
A more appropriate questions (as has been mentioned) is would Klein have won those games as a sophomore?
Plus, Sams will get the rest of this season to prove whether or not he is "the man" as you stated. I get the concerns because we had opportunities to win both OSU and BU and did not, in part because of Sams' mistakes. However, if he finishes this season with a 5-1ish record while playing 80% of the snaps, its going to be very difficult to doubt him and all K-State fans should be optimistic about the future with two years of Sams left.
