I agree with this - if you have three teams that have a squad good enough to earn £18m they are going to have a substantial advantage over those only able to offer a £2.5m total .
Although worth noting that the Sunderland squad in 2017-18 was apparently good enough to earn £47m.
Didn't help them much competing in League One in 2018-19 against teams who mostly ran wage bills 10% or less of that.
I'm getting repetitive and boring, but it just seems to me that these salary caps are formalizing a serious financial gap between Championship and League One. But if you look at the financial data, that gap has for the most part already been there for five years or more.......
