I'd be ok with this, especially if some of those R2-4 picks were in 2025, when it's possible there's a better class of S, LB and RB.
Having extra Day 2 picks when they host the draft would be icing on the cake for Mark Murphy.
There simply might not be anyone at 25 who is worthy of a R1 pick and they could get same value plus another pick by trading down.
Then again, I'm always on the trade down bandwagon and think about how fun having something like 6 R2 picks would be.
