Qb options going into the playoffs

So I need to look ahead to the playoffs, qb and TE are my only not rock solid positions. I have donnell and gates at TE so figure I can make it work but for qb I'm trying to stash 2, maybe 3 that can make it work.

Option are romo, cam, tannehil, flacco and Eli. (2 of those are already on my roster)

Cam and romo both have very easy schedules so was thinkin about rolling with them. Any qb's with favorable matchups I should consider or do you think I should pick a different one or two from the above set?

Thanks
