You said he would be an average premier league player. Therefore he would be good enough for most premier league teams that avoid relegation. The corollary being that if we had a team of other average premier league players, we would be comfortably safe. That is logic.
If that is so, then we are headed in the right direction. Were we to have an average premier league squad, we'd finish in an average position, i.e. around 10th. Although average, that would be a highly successful season.
