Should Desean Jackson Tell His Dad to "Sit Yo @$$ Down!"?

With the recent reports covered both by the Philadelphia Eagles and Cal Bears media regarding former Cal wide receiver Desean Jackson and the strain on his respective teams as a result of his family members' involvement, you kind of have to wonder how much is too much in terms of the parent involvement in sports.

Can the parents really be faulted for wanting to be truly involved in their son's life?Or does a young athlete have to at some point become his own man and do, think, and act for himself?
