From what I see in FAQ about training, there is training for 5 attacking skills, 3 defense, 3 physical , 2 kicking and 2 tactical skills.
Which are them ?
I will make a guess:

Attacking: Carrying, Passing, Catching, Footwork, Carrying, Positioning, Speed
Defense: Tackling, Blocking ,Positioning, Speed
Physical: Speed, Strength, Agility, Stamina
Kicking: Kicking , Punting
Tactical: Vision and Positioning

I excluded Intelligence skill, as I can see in the announcement about Intelligence:

We found out that the players are only getting low intelligence starting levels (similar to their skills) and this is a bug as intelligence itself cannot be gained by training.

Can someone please explain to me why blocking is a defensive skill and not an offensive skill in this game? That makes no sense to me.

Go out of your way a little and search the forum.

You will find a handful of threads based on this.
