Oh not you again.
Look, neither Davies or BOD were tearing it up. Gatland went with what he knew in the third test.
I suspect most people on here, if you go back to the lions tour threads of the time, were saying that Davies hadn't had such a good tour despite a great campaign for Wales.
Look, BOD got the nod for the second test despite there being a center who was in better form internationally and unfortunately did not perform well at all, he was very poor (again, uncharacteristically). Why does this automatically mean 'Gatland went with what he knew' in the final test? He simply replaced BOD with form many, the form centre in the UK and Ireland. It was a decision which had to be made, it was nothing to do with 'what he knew'. What a stupid cop out that is. For some (including me) he should have been first choice at the time ahead of BOD for the first two tests.
Edit - Response to your edit - The thing is, when a team loses that kind of is the time to make changes, is it not? Gatland made his changes, the team performed excellently and hammered the Aussies in the 3rd game, that was enough justification for me. Besides, the simple truth is that the perception that he was making changes for changes sake is only because he was picking Welsh players over the other nations. Perception will always be influenced by your patriotism and numerous other variables, like your self confessed dislike of the Welsh team for example. The same with BOD admirers. They have a perception that he is the greatest centre ever (maybe correct there) and find it very hard to stomach a young in form player taking his place when he doesn't perform. It is the same with so many on here saying that they no longer supported the Lions right from the start because Gatland picked so many Welsh players. It's natural, but doesn't give your argument any merit.
