Superbowl, need last second help!! WHIR!!

[greglee63]

I have 2 flex spots where I can move people around. Please help with the following 2 scenarios:

1. Who has a better chance of having a better day against GB: Nicks or Bradshaw? (or if possible are they both a must start?)

2. Flex spot: Tamme against Oak with Collie out, Choice against horrible AZ def but maybe splitting carries 3 ways, or Branch against Buf who has a shaky def but Branch fighting a banged up hammie?

Thanks!!
