You say that like it's problematic. Overall I'd expect that there's an equal chance of fat Botham showing up as there is of early Botham. It's a package deal. Depending on the stage of the draft, if that's a better package overall than the next best available option, I might very well go for him. He might win me a game single handedly and he might contribute absolutely nothing the next. Depending on the composition of my team and the philosophy of how I'd want my team to play, I might very well choose to pick him.Also, you rationale means that Ian Botham should never be picked as the odds of him being rotund and underpar are too great. Realistically, from 1985 to 1992 he was a shadow of his former self.
Honestly, I'm not saying that picking a player based on his peak is a flawed concept in itself. All I'm saying is that it's not the norm, and if the intention was to get people to vote based on that understanding, it probably should have been made clear right at the start so people could formulate their strategy accordingly.
