Shane and Fedor need to be at 100% to even keep it close.
Those 2 can also take a bit to get going. March them out there as much as you are allowed and let them find a rhythm.
Tyler has been really consistent and has been playing well lately from what i've seen.
After that it doesn't really matter. You're going to need MAJOR upsets to win further down the roster.

I like the idea of throwing some new blood out there to see if one of them can step up and play above expected.

Earl? No. Just no.
