That seems likely. Going through each useful attribute, then, here's my completely scientific prediction of where he'll be at the end of five seasons (plus or minus reality): ATH = 50; SPD = 70; WE = 100; ST = 75; STR = 50; TKL = 80; H = 60; GI = 60; E = 80; T = 70; and 3-4 IQ = 90.
I've never bothered tracking a player's development before, but I'm interested in doing it here and seeing just how high "sky's the limit" really is. At the end of each season, I'll make note of his progress.
