From an FF perspective, I don't hate either of these guys. NFL Championships mean nothing in FF, and if the opportunity cost wasn't so high to to obtain him, I'd love to have him on any roster...
SLIGHT HIJACK: POSSIBLE DRAFT STRATEGY
Depending on how your draft shakes out, I think there's a tremendous potential play in serpentine drafts (12 team Leagues or smaller), this year if you're in possession of Picks 1-3, perhaps even 1-5 depending on how your League scoring works:
Draft the RB that falls to you from LJ, LT, SAlex, and possibly Portis or Tiki, again depending on your League scoring...
If amazing value at RB/RB or RB/WR falls to you at your Rd2/Rd3 turn, and League scoring works to your advantage, trade your 1st Rd RB to the guy who drafted Manning in the 1st or 2nd (once again, where he goes will depend on your League scoring) for Manning. Depending on the acumen of that owner, you might even be able to get additional considerations...
I'd have to wait until I'd actually made my Rd 2 pick, and see what was falling to me in the early 3rd before pulling the trigger, but it's something I'm going to look at if I have an early 1st Rd pick...
Vick: once again, from an FF perspective, I don't hate him unless I own Roddy White or Michael Jenkins in a Dynasty League. Once again, if the opportunity cost is not too great, he's a quality draft pick if you can wait on QB, and can work him into a 3QB platoon, just based on what he can bring to the table with a quality start. I'd have to be drafting near a turn where I could draft a consistent but unspectacular upper tier QB (I'm thinking Delhomme, Bledsoe, Brees, TGreen, Plummer et al) and take Vick on the way back, and then grab a lower tier QB with upside (thinking Leftwich, Carr, Kitna, Big Ben) as insurance, but I think Vick is quite rosterable in a QBBC, with outstanding matchup play potential...
Now, from a non FF perspective, Peyton is not the Manning I hate...
...Eel-eye, however...well, I can't stand that punk...
