Upgrade for all Vikings skill players if this happens. Moss is a perfect fit for Favre and opens up everything for the rest of offense. With the way the D is playing this could be the year the Vikes get to the SB and actually win it.
I see the big upgrade in NFL terms (assumming the Pats aren't on to something about Moss' ability decline that we arent'), but I don't se the plus so much in fantasy terms - except maybe for Favre. Granted Moss will require the best defender giving the other WRs lesser coverage, but he will eat up a LOT of balls as well. There will be more offenseive plays, and more pass plays, but not as many more as the number of passes that will go to Moss - which means less targets to go around for the other Viking receivers. And similarly, there will be more TDs scored, but Randy will score more than the total amount those wil increase, meaning less to go around to the other Viking players than if Moss hadn't srrived.
I don't see the fantasy lovefest for other non-Favre Vikings.
