LEODIS MCKELVIN BUFFALO BILLS-IS HE THE REAL DEAL, OR NEEDS MORE TIME

LEODIS IS A WONDERFUL TALENT, BUT SEEMS HE SHOWED MORE DURING PRESEASON MORE THAN ANYTHING IN THE PRESENT.  HE HAS BEEN BEATEN A COUPLE TIMES IN THE COVERAGE, AND HAVE HAD DECENT RUN BACKS FOR FIELD POSITION, BUT NOT THE BIG RUN.  DO YOU THINK ITS BECAUSE OF HIS INEXPERIENCE, NERVOUS, OR HE JUST HAS TO GROW UP IN THIS LEAGUE?  ARE THE BILLS SPECIAL TEAMS FALLING IN THE RANKS, AND THE SEEN MAYBE LESS OF A THREAT ON SPECIAL TEAMS THIS YEAR?
