While I'm not crazy about Gore in Pittsburgh, how do you sit him right now? I love Jordan angainst cleveland, Portis though I'm not crazy about against the Giants. Dallas and Green bay, though they did get the rushing td's, didn't get a ton of yards against them. Fred Taylor could have a good game against Denver who's given up 90 yards to Lynch and 140 yards to Lamont Jordan, also consider Garrard will have a hard time throwing against Bly and Champ. Though you do have to worry about the splits with Jones-Drew I think Taylor will get more carries as he's been more productive recently.
You gotta love Smith against the Falcons and Galloway versus St. Louis, I think Fitz will struggle against Baltimore.
IMO I'd go with Gore, Jordan and Taylor in the flex with Smith and Galloway.
BTW is Mcdonald available in your league, could be a good filler for you in the future, he is leading the Lions in yardage! I'd also take a look at Welker!
But what do I know, I passed on Randy Moss in the 4th round!!!
