Thank you Jerry Jones ...
Jerry Jones, among the NFLs most talkative and hands-on owners, said this week that Dallas was likely to take more risks with Prescott as a runner in the postseason. He referenced the 49ers recent history against mobile QBs.
I think what you saw there (Monday) were going to get to see a lot of when we play San Francisco in terms of him keeping the ball and relying on that triple threat that he can have, Jones said on 105.3 The Fan in Dallas. If we could get it, if hes healthy enough to do it, his being able to instinctively take that ball and run with it is really a dimension that their defense has a difficult time adjusting to.

49ers know they need an answer for defending mobile QBs. Jerry Jones just added to the urgency.
Background (from the link):
The 49ers were 2-4 in the regular season when facing QBs who rushed for at least 250 yards both wins coming against Seattle and QB Geno Smith. Its fair to note the last of their losses to Fields, Denvers Russell Wilson, Atlantas Marcus Mariota and Kansas Citys Patrick Mahomes all occurred before the Niners launched their 11-game winning streak, though during that streak the Raiders game on Week 17 went to OT largely thanks to the legs of QB Jarrett Stidham.
