So you watched Cardiff regularly then? Or was it that you watched a few goals they conceded and attributed "blame" to Brayford solely based on something he didn't do, rather than the whole defensive unit.
Opinions....Brayford was not crap under Clough. He wasn't Crap under Adkins, but he didn't get forward the same as he did when he had Coady covering his runs and Harry at the back to defend. He came to the club to play for Clough and we then sacked him. You are dumbing down his ability to try and win an argument.
So far, Brayford has played 2 matches for Wilder. Save his crossing he's been good. That will get better.
As for injury....he was out for 6 months, missed pre season. That's 6 months doing nowt, with his leg in a protective boot most the time. He came back into a shit side under a shit manager with pressure to make an immediate impact. At the same time needing to get his fitness and strength back....not to mention form. He then missed the end of the season again, meaning he came into pre season with zero match fitness. He's still playing catch up. So yes, you clearly don't know how injury lay off affects form in actual human beings. These are not robots, or computer generated players. But flesh and bone, and every one different.
As for the maths...it's subjective. £250k in wages is one decent L1 player. If we have a fee to pay on top we haven't saved a penny and simply replaced the right back. And by saying we would save 10k a week for a year assumes Brayford is on 15k a week, which he isn't. You may forget how we were paying a portion of his wages when on loan, and didn't offer sufficient to cover half his Cardiff salary. Brayford chose to write it off. I can't recall the exact figure I was told, but £7k a week was the rough figure. (Will message you privately if you want to know how I know this)
So from that, he was on around 18k a week when Cardiff were in the prem. 50% cut....9k.....pay cut to come to us...£8k tops plus very generous promotion bonus. Even then....too much for a club in L1 BTW.
So we replace him and save 3-4 k a week. A risk not needed when other areas are a priority.
