Help with faab SP McCullers, Wright etc...

[price]

AL only 5x5 roto keeper league with QS instead of wins

Rank these pitchers by who has the best chance of sticking and be most effect rest of this year?

• McCullers (HOU) competition R.Hernandez and Oberholtzer
• M.Wright (Balt) competition B.Norris
• Klien (Tex) competition W.Rodriguez returning dwon the road from DL Harrison, Holland, Perez
• Marcum (Clev) competition T.J. House in AAA
• E.Ramirez (TB) Snell at AA

These are free agent faab guys in my league right now and I feel like going fairly high on McCullers.

Thanks
