I’m happy to get any free card. Most BND packs give you an option to get a lower non-BND so I don’t see the issue. I’ve got like 9 free cards playing on my 87 overall team.
In general, I’ve used the fantasy and token BNDs for offensive linemen and DTs since they tend to have the longest shelf life. My whole OL, DL and LB crew are BND and play great. Sure, I could upgrade them but they get the job done when combined with OP skilled positions.
