I read somewhere that Special Abilities don't work too well, so is that 16 skill points I pretty much threw away?

They have an effect. They just depend on the base attributes to be effective. Get your base attributes up and they'll become effective later.

No biggie.

What you want to do is decide what kind of LB you want to be. If you want to be a OLB, don't put any more points into D-General as you will never, ever use that skill. Conversely, if you want to be a MLB/ILB, investing in Big Sack probably isn't going to do much for you as you might not ever blitz enough to actually sack the QB (since you'll be going through the fattest people on the other team).

I would definitely get your speed softcapped ASAP just to take advantage of the free growth you get. Also bring agility way up. You'll need it.
