Whilst I'm as disappointed as anyone that McClaren's appointment seems imminent, I think we should give him a fair crack. The main criticism seems to be that he'll only tweak the squad, that he won't make sweeping changes and that his reign is gonna be tainted with predictability.
Firstly, we don't know exactly what has gone on behind the scenes. We don't know what his input is towards tactics and player selection.
Secondly, I don't think the team/squad is in need of a major overhaul. We have an excellent set of players and tend to do well in major competitions, we just seem to lack something - what that is I don't know.
Thirdly, McClaren has shown with Boro that he's tactically flexible and he's willing to give youngsters a good chance. How many other teams in the premiership play with wing-backs like he has done recently?
Fourthly, Who's to say that he won't make bold decisions like Allardyce or Scolari? He's already shown a willingness to drop his leading scorer Yakubu because he feels a Vidula and JFH partnership will be more fruitful. This is in a similar vein to Fergie dropping Ruud to accomodate the better all round Saha.
Fifthly, who's to say that he doesn't want the job as much as Allardyce? Allardyce is undoubtedly a more forthright manager and his method of application will naturally reflect this
