He hasn't been any good since he injured his pec, except for last season's finals. Which shows he is capable still. The interview during the week, when Nathan was asked if he gets angry during a match and gives team mates a spray, was pretty telling. He said it depended who it was, and whether they'd take it positively or not. I think Tago might be mentally fragile and they have to be careful how they handle him. Dropping him might break him. But at this point he's such a liability that doesn't matter any more. When the opposition run straight through him and score early in every match, the whole teams moral drops.
