I'm still debating. He's either going to be a goalie or defensive back. His EQ% for goalie is 93.76%, and defensive back is 95.25%. So almost the same.
I just have a 22 year old goalie with good CL that I've been building up with EXP and season bonuses.
I think he would be more valuable as a goalie, but has 100 FIP already, and I don't think I could build up his EXP and my other goalies at the same time.
