Exactly. Lowe thought he could substitute paying for a number of decent players by paying for one sports psychologist and somehow would unlock some sort of subconscious enhancement in ability in the poor players available as a result.
As for the quality of sports pyschology, he may well be a household name, but all he did for the Rugby was assemble a team of others to do the work.
Even if Lowe's cheapskate theory had any merit to it, he appointed the wrong person in SCW, since the team performances would all be about him than the team itself.
