Never really noticed this but seems like a good/valid point. I really like Katoa as a player but our defensive performances have dropped with him as hooker. Likely to be some sort of connection.
I also think Tamou is crucial to our defence. As soon as he went off yesterday our middle started to crumble. When he came back on it tightened again.
Have they though? We held the tigers than dragons scoreless with Katoa starting at hooker, our best defensive performances of the year. I think its just an easy connection for people to make because Wal was such a great defender, but there was no initial drop in our defence when Wallace got hurt, if anything was at its best just after that point.
Sure the defence seems to have dropped off since Wally retired, but he was out for weeks before he actually retired.
