Both Leach and Jones for Houston?

The way that a number of NFL offenses are progressing, the need for a fullback on the roster is minimal, to the extent that some teams don't roster a player that is dedicated to that position alone. However, given the number of teams that have already reached out to recently released Vonta Leach in the short time since his dismissal by the Ravens, it's obvious that there's still an appetite for such a player in various NFL outposts. One of the teams mentioned as being interested in Leach is the Houston Texans, his previous employer; however, they already signed Greg Jones this offseason. Problem? Maybe not.
