Yep and Sexton was on the pitch for 80 mins against Australia and we beat them
And in the last match of the Six Nations he was outstanding against England.
I think O'Gara has been perceived as a weak tackler since the 2001 Lions Tour. I believe NSW tested his face out a few times too. How many times have we seen back row moves from the tail of the lineout that involved walking over O'Gara. I remember Parisse and Harinordiquay (?) doing just that in recent years. He does tackle he's just not very good at it and it takes its toll. Its not a bad thing, the Aussie out half sinks back into full back for defensive lines. And you could say Wilkinson tackles too much or too hard hence the injuries

FYI - I think we are lucky to have both and I am a Connacht supporter, we are going to win the H-Cup this year!
