Rex had words of praise for Coleman in man coverage... and Cole will be on the PS for the seaon (except of course when he is activated like now). My guess is Carroll is the one they'll be letting go for Ivy, which would be a shame because I think he's better than Coleman... but I'd take Rex's opinion over mine
PS I think all of this is being made for the game we have against NO. We activated 10 DBs for the Pats and I would expect no less for Brees&co. I'd feel much better with EITHER Coleman or Lowery on the field, and not both, while Ivy is the nickel back. I have no idea why they looked at Miller though... I think he is no better then what is already on the roster.
