Oh, ya, you're missing something.
Note, I currently count myself among the side that says excusing Solo is not unusual, nor incorrect from what we know. It might be a little preferential, if you looked at historical incidents of similar magnitude, but I think not much.
However, could Solo benefit from dopage? You betcha. It wouldn't be EPO, as you have realized, endurance is less important for a goalie. However, reaction time, and strength are hugely important for a goalie. Both can be enhanced via doping.
