OP was a good read but may ultimately be totally useless in determining how good or bad this man will be with a transfer kitty. HE will have no say in who we sign, these owners have made that very very clear on more than one occasion. Rogers is there to coach and nothing else. The DoF will decide who we buy. As the owners have said 'the coach will be present at the final interview only', that will be his involvemnt in buying player - zero.
So, forget about how good or bad Rogers is at spotting talent and developing players once signed, or how he will deal with a transfer budget, it is not his concern.
