Yeah, if trained properly, he can be a useful player for our NT. 20 year old trainee is still worth training. I had a player whom I bought for around 200k at the age of middle 20, then trained for 2 full seasons and sold for around 900k. So with the right training, he can be a valuable player (maybe a SF, looking at his height, but may specialize in one area since he's already reaching 20).
