Kuale can always step in and play DL. We also have Quinn Everett and I believe Kyle Norris could also play on the DL as Nationals, in a pinch. Louie Richardson has been playing quite a bit and he's a National.
If Sears is sidelined...,
... I'm guessing Suber goes in as DI
... or Suber starts at field side HB and Johnson rotate with Sherman (who will make his 3rd start) at the SAM/Dime
... while Frazer rotates with Richardson on Vega's spot.
