It's actually a good question to ponder.
Hollister had some ST value when he was healthy this season, but not much at all on offense as either a blocker or receiver. He was a healthy scratch for wk-15 @PIT, and then hurt his hammy (again) after wk-16 (BUF).
For all we know, Anderson may have been getting some reps with the first team offense since before Christmas. Hard to imagine that he'd be worse at blocking than Hollister, and he does have some significant receiving experience.
With the Pats having only three actual WRs on the roster now, and with Gronk possibly not completely healthy, an extra target who can block may be helpful, at least as a potential outlet target and in-game injury reserve.
OTOH, if Rivers, Clayborn, Kamalu and Davis all sit, that leaves only Flowers, Wise, Simon, HT and KVN as potential edge-rushers. I suppose that Crossen could sit instead of Rivers (or Kamalu). The Pats would still have seven DBs active, although it would be a small hit on ST (two units).
So, IDK. Seems like a few different ways this could go, but I think the Pats are thinner at offensive skill positions than at DB or Edge.
But then, Rivers sacking Rivers would be kinda cool.
