PPR league, I picked them both up as FA so they count as my 12th round keeper. I feel like you can always find decent WR but steady, plow horses like Grant with great late season stats is the better keeper? Plus I am not confident Favre and Rice will repeat that incredible run.
i'd definitely go with grant. rodgers can have a terrible season and grant probably just benefits. favre has a bad season and most likely, so does rice. tavaris jackson throwing to sydney rice isn't something i'd want for my fantasy team...and it's a real possibility.
