Before anyone freaks out I am not talking about Leodis as a starting CB. Leodis McKelvin is a free agent NB and return man for the Buffalo Bills. The Bills are deep at DB and return so they are going to let him walk. He fills two needs for the Titans. We need a serious improvement at NB which is a vital position. Leodis is also one of the best return guys. Meaning we can fill two needs with one roster spot. What a concept. Mariani and Reynaud both contribute little in addition to their return abilities. Some will say Mariani looks like he can be a decent slot receiver. But he has not shown it so far. We already know Leodis us a good NB. If Mariani ends up showing he is a good receiver then great. Keep him. We can always use a backup return guy just in case.
