Fred Jackson or Ronnie Brown (weeks 15,16)?

You'll want to keep Freddy, no question. As the lead back for Buffalo the past few weeks, he has been simply dominating. Yesterday against the stout Steelers defenses, he was a stud. He's now scored at least 22 fantasy points in three straight weeks (in standard scoring). He is approaching must-start status. Brown has been trash all year, yet he continues to be overvalued week-to-week (the exact opposite for Jackson). Unless the other person in this deal specifically said "I'll take Jackson or Brown" though, it'd be pretty stupid of him to be willing to take Brown instead of Jackson.
