Obviously pick up both Boldin and/or Mike Williams if you can. If not, then your best option this week is probably Manningham because Buffalo's secondary will give up yards and the matchup has potential to be a shootout.
I'd rank your WR2 options in this order:
Boldin, Tampa Mike
Manningham, D. Nelson, Crabtree
James Jones, M. Thomas
