A few clubs will definitely not have voted in favour of that - Chelsea in particular I would imagine. I think Todd has spunked something like a billion in two years on 28 players?
A normalized spending cap will definitely hurt some clubs more than others, that said it just means everyone runs the same speed but the bigger clubs definitely start further ahead of the starting line. Overall I am in favour of such a thing and would certainly approve of it in the EFL as a broader whole.
