First time asking question - any advice

[newguy]

Got the following team - not sure whether I go with Welker over Thomas, Spiller, Martin, or Charles?

Any advice:

Start 4: Welker, Spiller, D. Martin, J. Charles, Demaryius Thomas

easy to say now but i u have to start welker and thomas for sure and spiller vs jax. martin vs charles a toss up but charles better matchup so sit martin, thats what i would have said
