I also use spreadsheets, for scouting, for recruiting, and for game planning, and even one for projecting how many games each team in my conference will win in conference. For recruiting, I project out future ratings and rank players based on a formula I've developed to rank players for each position that I built them from scratch. The formula definitely drew on commentary from the forums re relative value of attributes at various positions, from which I developed 4 different original formulas to see which seemed to be better over time. I ended up going with a tweaked version of one of them that I am pretty happy with, but look at it again every season. As I am only in one world, the spreadsheets aren't as automated as they could be, though. Honestly, working on and refining various aspects of these spreadsheets is the source of a large part of my enjoyment of the game.
