Warnock is currently averaging 1.62 PPG, which is a very respectable 75 points extrapolated over a season, and we'd have pipped Sheff Wed to a playoff spot last year. This puts us on track for 65 points this season.
If we beat Rotherham, this rises to 1.67 PPG, and 77 points. Having said all this, as NYCBlue says above, Sheff Wed are on target for over 80 points, which is going to be a massive total to get into the playoffs, Hull got promoted automatically with us in 2013 with 79 points!
Either way, if we can hold onto our best players, buy a few more (namely a keeper and a striker to challenge Zohore), I think we've got a real shot with Warnock next season.
