As long as they are issuing more miles than they are redeeming, they'll be in good shape. I have almost 200k AM... I book economy for all my flights and would be lucky to redeem even myself to J.

You can, but (i) you need to be flexible on the flights, (ii) J redemptions are easier on short hauls and regional, and (iii) upgrades are easier than full redemption.
