Farve Dirty Play?

In a preseason game on August 31 between the Vikings and the Texans Brett Farve made an illegal block. With this happening commentators and journalist are having a field day calling Farve a, "Dirty player", "the little girl Esther from 'The Orphan'". Before they start ridiculing Farve they should take a second and look back on his career of never being a dirty player from what I can remember. Also the fact that the man is practically reaching the age of having to use a walker, all we was trying to do was make a block. Sure he might have gone a bit low but lineman get called for that penalty alot too, why we not giving them the same crap?
