Sounds to me like your problem is with the wider economic state of football in general and not with Brewster.
He may achieve practically "fuck all" but he's not doing practically "fuck all" - otherwise Wilder would pick Oné or Marsh ahead of him. Unless Wilder is an idiot as well?
He can't help what he was paid and he's sure as hell not about to turn around and give it back (who would?) but it's not his fault that the wages in football are totally out of sync with the real world.
It's the same reason I haven't bought a shirt or a season ticket this year, and haven't bothered to go to many games either...it's extortionate and absolutely ridiculous and I'm not up for paying through the nose to fund millionaire lifestyles.
Do I blame Rhian Brewster for that? No.
Do I want him to continue representing Sheffield United? Also no.
But any young person who has a dream and works hard on achieving it, then has their dreams scuppered through injuries, poor luck and being elevated above their level by people in their industry...you've got to feel a bit sorry for them.
Would have benefitted from a decent transfer to somewhere he could be developed and have good players around him...anyone who thought he was ready to be a line leading striker for a top half Premier League team (that desperately needed a goalscorer) was off their heads
