These were obviously meant to be previous lives of the Time Lord called the Doctor.

And yet Susan's grandfather calls himself the First Doctor and the cricket player calls himself the Fifth.

I don't think you can say for certain that those guys are previous lives of Doctor from before Hartnell. I think from the way Hartnell's self(aren't all of them Susan's grandfather?) and Davidson's self talk in "The Five Doctors", it is pretty certain that Hartnell is the first doctor "The original you might say" and Davidson is the fifth "regeneration? fourth. So there are five of me now"

And if so guys are doctors, why didn't Borusa pick them up as well with the time scoop?

As for the Valeyard, he comes in between the Doctor's 12th and 13th self.

As for the guy that helped Tom Baker's self regenerate, I don't he is meant to be considered one of the doctor's lives.

And what are you saying was reconned?
