Question : what makes Douglas so much more attractive to chase than any of the players above? Why him, and not the others?
Kane played under Chris Hickey and Michael Foley yet never really reached his potential until Chieka became his mentor. Chieka rates Kane and Kane likes working with Chieka.
Link didn't rate Kane, so didn't offer him a top up, Kane then signs for Leinster. Chieka was livid, as a few articles from this time last year will corroborate.
Link then falls on his sword, and Chieka becomes coach. (At the time, I heard that his conditions were that KB (Kurtley Beale) Gits and Kane would be in his RWC squad). Chieka is now in a position to offer Kane a top up, and wants to do so.
Kane fits in well with the way Chieka likes to play. He was a real unsung hero and really well liked by the Tahs squad. At the 2014 end of season dinner, Dave Dennis got up on stage and made a presentation to Kane, which no other departing player got.
Chieka is just picking the players he feels we can win a world cup with.
