Move for Mopportunity or stand pat?

Just had our auction draft on Sunday and for the most part I’m quite happy with my team.

However I really wanted David Montgomery as well but was outbid by this guy

He’s a big packer fan so I could move Adams & maybe Peterson to get Mopportunity and either T.Hill or K.Allen. Worth it? Or should I stay with what I have for now and see how the season unfolds?

BONUS QUESTION: Both LAR back-ups are on waivers. This is a 12 team, 9 starter, 5 bench league. Should I drop Peterson and grab Brown or Henderson?

Thanks Clan!
