The projections that are up right now are far from final.
That said, here's why last week's 133/2 outburst should be viewed skeptically.
Baltimore ran the ball a ridiculous 47 times out of 61 plays last week (not including sacks). That's just over 65% of the time (in a 14-point win). In their previous games this season, they ran the ball 48% (win), 37% (loss), 46% (win), and 42% (win).
Sixty-one total plays is about right. They are three-point dogs to the Patriots. Based on that, as well as the Patriots' relatively weak pass D, I'd expect them to run the ball about 41%–42% of the time. That gives them about 25 runs (and 36 passes).
Rice won't get all 25 of those runs, of course. He got about 57% of his team's runs last week (27 of 47), and he now has just under 55% of the team's runs this season. If he gets 14 of the team's 25 runs this week, that would be 56%, which seems about right as a first approximation.
On about 14 carries and (by similar reasoning) about 4 targets, he could do some damage; but it probably won't be anywhere near what he did with his 31 touches last week.
If the Ravens get ahead of the Patriots 17–0 midway through the second quarter like they did against the Broncos, and hold the lead the rest of the way, Rice could get well over 20 carries again. But I think the more realistic scenario has him getting touches more in line with what he got in weeks 1–4. Willis McGahee and LeRon McClain are still likely to collectively get at least half as many carries as Rice; and that limits Rice's prospects.
But read the bold at the top again. The projections may change throughout the week.
