I think you missed my overall point. I said in the post you quoted that I'm aware how much it happens, I know a lot of the inner workings and appreciate those who let me know what's going on.
What I said was I don't necessarily agree with that being a good recruitment policy. You said "that's right across the leagues, more so at our level". That comes back to my point again, we want to be a top 30 club and yet still operate like a lower league club.
Clubs like Brighton and Brentford were in League One in recent history and completely overhauled that recruitment strategy and employed substantial recruitment teams. Players were only signed after a thorough and rigid recruitment process that analysed fitness, suitability to a style of play and statistical performance. I can assure that was little to none "Hi, I'm the manager of X club and want to know who's available on your agency". Players were identified in house by a large recruitment team, they employed "managers" as head coaches to work within that setup and it paid dividends. Those players that signed all fit into a model and not only got them promoted to the Championship and PL, but also made them substantial profits whilst doing so.
I think this goes back to my point on an older page, stating this is not bashing the club, or bashing the manager, or bashing any members of staff that may be families or friends, it's simply stating that major investment in those areas are required if we want to be a top 30 club. Robinson could choose to work under that or may not want to, in which case we find someone who does. See example below:
"Warburton finished his Brentford managerial career with 40 wins, 16 draws, 22 losses and a winning percentage of 51.28%, the highest of any Brentford manager.
[66] He departed Griffin Park upon the expiry of his contract on 30 May.
[67]"
It was later discovered that one reason for Warburton's departure was that he vetoed any incoming transfers during the 2015 January transfer window, only sanctioning the signing of an injured Lewis MacLeod.
[68]"
Familiar story... successful manager reluctantly let go as he didn't want to work within a certain model and recruitment strategy, in comes Thomas Frank and they spend a few years going for promotion and end up in the Premier League.
