This is for off topic isn't it? Oh, hang on, I see what it's about now...
The other teams were tactically quite different. While I think you could probably put Watkins and Yorke more or less on a level (if Watkins keeps going, he may surpass Yorke for me), I don't think Yorke would work as a line forward in the same way. Likewise, Bailey gives us what we need now, Young have us exactly what we needed then. I don't think Young would work as well in this team, and I'm not sure Bailey would have been as effective in Young's team
