depends.
also this is 1 point of dicussion amongst topics about which there is the most diffrence in opinions.
some don't value it too much and find other skills much more important so they will never train it.
others think it is also needed and train it along with the rest of the skills for inside players.
It helps, and higher blocking skills will also help the other inside training to go a little faster.
The question is: is it profitable, this means, wouldn't it be better to just train the rest anyhow, even at a little lower speed.
I think everyone has his own opinion on this.
I think it is worth trainnig, I also know a GM who thinks it's not worth it.
Maybe if many others give their opinion you get a better view about how many value it and how many think it's a waste of time...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
