The Waratahs’ mid-season dip isn’t the only headache developing for coach Dan McKellar, with the Brumbies targeting the Tahs’ most experienced five-eighth, Tane Edmed, as a replacement for departing playmaker Noah Lolesio. After winning their first three games of the Super Rugby Pacific season, the Waratahs crashed to a third loss in their last four via a second-half capitulation against Moana Pasifika in Auckland on Saturday. Leading 21-7 at halftime, the Waratahs defence wilted in the second half as the Ardie Savea-led Moana Pasifika side scored six tries to win 45-28. The Tahs’ tackle effectiveness slumped from 87 per cent in the first half to 75 per cent in the second, where they missed 20 tackles. The Waratahs have conceded 102 points in the past two games and with competition leaders the Chiefs next up in Sydney on Friday, defence will be a big focus for McKellar this week.
