Keeper advice / 12 team PPR

Current have Lamar, Bijan and Cook set as keepers.

From there, these are the best remaining options available:
Burrow
Pickens
Kyrie Williams

If Lamar is healthy, I’m loving what he can do. Just worried that he fell off last year due to injury and him scrambling opens him up to that even more. Burrow is fantastic when healthy, but he can’t stay healthy.

Kyrie had a good season last year, but loses out on goal line touches.

I feel like I can probably have a chance to redraft Pickens.

If I don’t keep ANY 3rd player, then I’ll draft one round earlier and can potentially pick up someone else altogether. Not sure who’ll be there yet as keepers aren’t locked.

Just trying to decide if it’s worth going all in on Lamar, because the risk is absolutely worth the reward, or roll the dice.
