NT is a the DT that anchors the line and generally gets doubled team by the C and a G. Normally, you want the NT to have a lot of strength to not get pushed back and destroyed by that double team. DT's usually get to go 1v1 with a G, so you can try beating him with a more "Elusive" build to get to the QB. The soft cap is 48 for every attribute, meaning that it takes 1 SP to raise that attribute by 1 until 48. After 48, it costs 2 SP to raise the attribute by 1 until you get it to 60, where it becomes 3, and so on. The trick to maximizing your SP and attribute gain is to soft-cap and attribute ASAP. That way, when you gain your automatic attribute bonuses from lvling up, you get more out of it since it's boosting an attribute that would normally take 2 SP to raise versus and attribute that would only take 1 SP to raise. It's kind of complex and I did a crappy job of explaining it but I hope it made it a little clearer.
