Waller or Lamar Jackson?

PPR Keeper League (Keep 5 players per season)… Would you keep Waller for a 3rd or Lamar for a 10th?

I plan on keeping:
JT for a 2nd
Henry for a 3rd
Evans for an 8th
Michael Thomas for a 9th

Also considering throwing Evans back and keeping Lamar. Any thoughts? (Round determined by where you originally drafted them or by ADP for a FA)
