Fair points, although I think the main issue that people have with Bazunu is that, statistically, he's one of the worst keepers in the league. (Of course, we can all accept or dismiss stats to back up a given point of view...). I don't think anyone has accused him of never making a decent save every now and then....?
The one question I ask those who stick up for him is, putting the stats to one side, where do they personally rank Bazunu amongst his goalkeeping peers in this league? Top 5? Top 10? Or, another way of putting it... If you could have a choice of all the goalkeepers in this league to play for Saints, how many would you choose before you got to Bazunu?
