Etienne, Roberts, Robinson, Collins, Lassiter and the DL are the biggest losses.
Etienne because he’s really good and not obvious who will replace him.
WRs and DBs because they are really good, though there is great depth at those positions so there probably won’t be an enormous drop off in production.
DL is going to be rough. There are other guys there (Po’uha, Asiata, Schoonover, To’omolotai, Taumoepeau, Singh, etc) but we will probably need to hit the portal for depth in nothing else, and finding great DL in the portal isn’t easy.
