The Munro criticism always comes down to two things. He is prone to absent mindedness, so can make glaring mistakes. Also his pass completion (unless it's to his CB partner or GK) is horrendous as he just hoofs it.
However, his pros are leadership (will likely be club captain after Slater's departure) ability to win headers and he's strong. He also has been a Forfar player for quite awhile, second only to McCallum (with Matty being released).
Andy Munro is totally suited to playing centre back for a Scottish League 1/2 team. Should he have won Away Player & make the TOTY? Probably not, but for all big Andy's faults he will be an influential player for us next season.
