You can have a lot of s***** depth. its pretty easy. Just acquire nothing but AAAA players from other organisations while giving away trade chips, then patting yourself on the back. I.e. Pannone has a FIP of 5.3 in over a 100 innings at the MLB level. Is that depth, you can at anytime find guys who will do that for you.
Depth is when you have above replacement talent, not below.
