My first reaction was "oh nooo". He's a relic from the bad old days of stampkar rugby, though superb in line-outs. Also, he doesn't seem to have the intellectual wattage needed to think through the smart moves needed to get past the New Zealanders.
Letting him near the Lions makes me nervous. I hope I'm wrong and Victor "Kiep on the Preszjir" Matfield has grown during retirement.
