Logic would indicate it's little surprise you've no concern about an unhealthy link with an agency that provides us with the majority of players recently, seemingly.
Whilst you correctly point out Giles and McGuinness are good players, it raises the question if we would even have looked at them if they were represented by other agencies. The question is also applicable to Doyle, because it beggars belief that any positive evaluation of Doyle could have stemmed from this seasons loan debacle.
Logic would also indicate that fans do indeed care about the club seemingly being reliant upon one agency. Is it the case the club are researching players or simply, in the majority of cases, simply going with what an agency offers?
