To be honest, I think statistical analysis, or software as you call it, will be better than humans at identifying players if it isn't already. Humans have lots of inherent biases which effect how they view a player. Are they too short? Do they run funny? Do they look clumsy on the ball, or maybe a little lanky? Software using statistics will cut right through that, and will better be able to identify the players that fit your team, without human biases coming in the way.
The issue right now is collecting enough data, and applying it effectively. I am certain that as time goes on, these systems will get better and better, and anyone not using it will be left behind. In time maybe machine learning will be applied in the shape of neural networks as well.
