Ok so I have already clinched a playoff spot and MJD is my 3rd/4th best RB this season.  I also own Matt Forte, Gore, Chris Johnson.

In this PPR dynasty league, we start 3 WR 2 RB and 2 flex, so I always (barring injury) start those 4 RBs.

My current WR are Boldin, Greg Jennings, Ocho and Braylon Edwards

I had an offer on the table of Run DMC and Calvin Johnson for my MJD and Antonio Bryant

Doing this trade will cause me to NOT start 4 RBs anymore and instead starting 4 WR.  Does this trade make any sense for me? I have a great shot at winning this league fwiw, so I am thinking  if it aint broke then dont fix it.  It is just hard to turn down Calvin for me, even if MJD is a top 10 RB.  I turned this deal down, but am wondering if I should try and get it done.

I agree with Tav, if you want to win this tear, then dont do it, but looking ahead then you would
