McKelvin only had 17 tackles and a pick as a freshman, but averaged over 25 yards per kick return and 12 yards per punt return to have an immediate impact on the field. As a sophomore, he had 30 tackles. He began to blossom as a junior, finishing the year with 66 tackles and an interception. He closed out his career with 60 tackles and two interceptions.
McKelvin has all the physical tools to be a standout cover corner. He is an excellent athlete, with excellent quickness, and great speed. He has the hips to turn and cover receivers down the field, and in out and of their routes. His explosiveness also helps him on special teams, where he is a major weapon as a return man.
McKelvin is not the most physical corner. He will need to get stronger and show more of a willingness to get tough with receivers. He is also too aggressive at times, going for the big play instead of staying within himself.
McKelvin has risen up the boards with a fine senior season and his excellent overall physical ability. With a little time, his talent could make him a standout cover man in the NFL. He should hear his name called in the first round at some point.
