Admitting that you're wrong is never a bad thing and no one is perfect, every person got an opinion and he's entitled to it, as long as i respect your opinion you're supposed to respect mine.
From and objective point of view. Molinaro isn't nearly as bad as you make out. He was quite good defensively and at times very good. The whole season you could see he improved in that department. Sure he can't cross for shit, but its not exactly his job as a defender anyway if he stops his opponents from scoring then I'll be content until we get a new LB who can do it all.
