I've been offer Mark Ingram for Frank Gore straight up. Here are some of my thoughts:
PRO:
1. Ingram is much younger (I'm in a keeper salary league)
2. Ingram is cheaper ($27 --> $32 next year, which if he produces, would be fair value), Gore is $36 ($41 next year)
3. Ingram is in a better offense.
4. Ingram, even though he's coming off knee surgery, has a lot less wear and tear than Gore
5. Ingram has the better playoff schedule.
CON:
1. Gore gets more touches
2. Gore is in a run oriented offense
3. Gore will catch passes (we get bonus points if RBs catch TDs)
I think that Harbaugh is going to run Gore into the ground this year, but then again, I don't think that the Saints moved up in the 1st to draft a RB so he can watch Pierre Thomas & Sproles
My other thought is that if I do acquire Ingram, I can play the matchup game with Ingram & Woodhead until one emerges.
I'll answer yours.
