Here is just a basic starters guide that will yeild very good players.I am going to assume you know or have read some basics of slowbuilding, if you don't then find them and give them a parousing.
Start by making sure you are not creating your new dot until day 40 or 41.
At creation, decide what you plan your character to be like. Decide at least your first 5 cap order (the abilities you will raise to its cap point , be that 68 or 77 etc.) .Your first 2 should almost always be primaries of the position and archetype you chose.
For instance my CB is capping Vision 77, speed 81,agility77,jumping 73 in that order (for you vets, i know vision first isn't optimal).
At creation make sure your first cap stat is raised to 25 and your secondary gets all the remaining points, this is just at creation, do not use the extra 15 SP you get after creation yet. If posible, use heigth or weight to get an extra +2 to your first cap stat. Upon creation immediately buy the 10% increase for your first cap. Train on normal until the first cap stat reaches 30-33 and has the training bar above 85% . You should be able to achieve this before day 1 of season. Use skill points to raise this above 48, and continue raising it to your cap pre-chosen cap point. (here is a link if you aren't sure of cap points =

Now choose your 3 quad trains to unlock. This will depend on your preferences, and cap order you choose, there is alot of wiggle room on strategy here, after experimenting, i find it best to try and include the stat you will cap second to the list.
In the example above i chose Speed,agility,jumping. You will be able to change the 4th quad train as you wish, and it will still recieve the +30% , so that is very helpful. I recommend at this time also unlocking the 10% increase to all 3 abilities you have chosen as quad trains. Save your coming BT for another 10% increase to your second cap stat as well.
Now begin quad training by no later then day 1. Its slow, but with natural level ups, by the time you reach your first stat to its cap point (note for this method, your first capped stat must be capped to at
LEAST 73 ) you will have your secondary to about 31-36, begin capping it as soon as you have finished your first cap. Continue this process till you reach your cap goals. Switch up the extra quad train from year to year to balance out your build and take advantage of the free +30% while they are at their lowest. After 3 years of quad training you should have a good start, and your cap order all ready to cap. You can then switch up to a couple years or light training, or continue to quad for up to 3 more years, or any mix there of. You just cannot quad for more then 6 years total or you will not have the appropriate amount of BT for gear.
There aren't any secrets to player building. It's not about ingenious and creative ideas so much as it is tireless, meticulous planning that leads to maximum efficiency.
