Depth an issue?

So I'm pretty stacked at RB in my 10-person standard league with:

Murray, Hill, Randle, Gordon, Abdullah, and Freeman.

My WRs are:

ODBjr, J Matthews, Landry, John Brown, and Eddie Royal.

Should I try and trade for a little more depth at the WR position? I think Royal, Brown and Landry all could blow up but it's way more boom/bust than I'd typically like.
