Robinson is just stabbing in the dark. Here are the exchanges via Twitter:
Brandon Jacobs has never been a Pro Bowler. It's not him.
about 11 hours ago via web It's not DeAngelo Williams. Nor Maurice Jones Drew.
about 11 hours ago via web @Todd_Wright McGahee is possible. Along w/ Marion Barber and Marshawn. Key is the trade fit within each division. Hope 2 know more tomorrow.
about 11 hours ago via web in reply to Todd_Wright It's most definitely not Adrian Peterson. Not in a million years.
about 11 hours ago via web Yes, eveyone is correct about Marshawn Lynch. Forgot he was Pro Bowl replacement. A possibility, though I have 2 wonder about his value.
about 11 hours ago via web Yes, RFA's can B traded. But that's not scenario that was described to me. It's not a team simply signing someone away and shipping a pick.
about 11 hours ago via web It's not Frank Gore. And both Ronnie Brown and Leon Washington are RFAs. Marion Barber still fits the description most accurately.
about 11 hours ago via web The RB isn't Ricky Williams. Ricky doesn't have the trade value.
about 11 hours ago via web Will B at Sam Bradford's showing 4 teams in Oklahoma. Hoping 2 talk 2 execs & flesh out pro bowl RB that is supposedly on the trade block.
about 12 hours ago via web It's not Joseph Addai. I checked into him. And the 49ers love Frank Gore. I don't think there's any shot that it's him.
9:09 PM Mar 27th via web Yes, unfortunately the source for this tip was vague, but they had good reason to be. The source always has great info, though.
9:07 PM Mar 27th via web It's not Leon Washington. Injury concern & he's available as a restricted FA. Marshawn Lynch never been Pro Bowler. Ronnie Brown? Possibly.
8:51 PM Mar 27th via web The running back definitely isn't Steven Jackson. Absolutely not. I checked into him. He's not going anywhere.
8:31 PM Mar 27th via web Initial thought was Portis, but his trade value just isn't very strong. But factors around Barber (contract, split carries, etc) make sense.
8:20 PM Mar 27th via web I don't know the destination. It was an ambiguous tip. Have been trying 2 nail down the RB and the 2 teams for a week. Barber fits the best.
8:17 PM Mar 27th via web Agree, extremely rare a pro bowl RB is dealt within his division. But I'm told that talks are occurring. Barber fits the scenario the best.
8:14 PM Mar 27th via web Barber is a little younger than Portis (26 vs. 28), has less mileage and is more explosive. Injury factor is probably a wash at this point.
8:12 PM Mar 27th via web I don't think the RB is Portis. He doesn't have much trade value. Barber, on the other hand, does. And he's making too much 2 B a share guy.
