I agree, it does strike me as a little bit odd. Of all four of our guys Hogan, Edelman, Amendola and Mitchell, only Hogan appears to be fully healthy - - and even he was dinged with a shoulder issue somewhat recently.
I have to imagine McDaniels will feature Gronk, Bennett, Derby/Harbor, plus Foster and White in the pass game. That may actually be smart... 3 TEs, plus White (or Blount) and Foster on the left and right of Jimmy. You could run the no-huddle out of this set and keep the RBs in for pass pro to pass to the TEs, or split everyone out and go 5-wide, or keep everyone in and go power run to Foster or Blount...
