Is this a fair trade?

Andrew Luck, JStew, Nate Burleson for Ryan Matthews and Fitzpatrick...

Guy trading Matthews needed serious help at QB...my team is already stacked so I figure I'm going to catch flak for getting even more stacked by trading my backup QB so I wanted some outside opinions...

i won't call it fair, it's more of acceptable with big disadvantage trade, however, acceptable.
i do not know how many teams are in your league, but if it's anything less than 12, i would definitely keep R.Mathews and pick QBs from waiver if i am the owner of R.Mathews

It's a 12 team league.
