He was the reason that Leeds team were so good.
I wasn't around but whenever I read about Bobby Collins I always wonder why we sold him.
There's not many others aside from Alan Ball that it hurt to sell.
Catterick had a few rules
1) If you spoke your mind and were 30 he'd get rid asap...Collins, replacement Stevens, then Kay.
2) If you spoke your mind and he had a replacement - gone asap...Gabriel, replacement Kendall
3) You weren't doing the business - gone asap...Young, Vernon, replacement Harvey Pickering, replacement Royle
4) if you spoke your mind but were doing the business rule 3 didn't apply - until it did.
If you were borderline 1, 2, or 3 and / or he could get good money for you - gone asap...Ball*
*the Ball of late 1971 allegedly with gambling problems was not the Ball of 1966-69...and he doubled his money, good business.
