Need 3 WR: Welker, E. Royal, Marshall, Walter

[Whisper]

12-team, 1PPR league with 2 WR spots and one W/R spot (sitting LT this week, so the flex is going to a WR while Benson fills in for him):

Welker @ NYJ
E. Royal vs. Cleveland
Marshall vs. Cleveland
Walter @ Tennessee

Right now, I have Welker (the one obvious choice), Marshall, and Walter in...I figure assuming Walter comes back this week, he should be targeted at least a moderate amount by Schaub. And given the coach's praise for Marshall's efforts last week, in addition to his being targeted in some important situations, I'm wanting to plug him in as well.

But Royal is generally a bit of a PPR beast (except for last week), so it's tough to decide whether I should plug him in instead of Walter or Marshall.

Thoughts? And thanks.
