I've worked out the Strength of Schedule ranges for every team that has a possibility of finishing with 5 or 6 wins. Each SOS number is given in terms of number of opponent victories. Divide by 256 (games in a season) to get percentage if you prefer decimals to nice round whole numbers 
6 win scenarios:
Minnesota - 117 to 128
San Fran - 123 to 132
Washington - 127 to 134
Houston - 127 to 134
Miami - 134 to 142
NOTE: Though HOU's max and MIA's min are officially the same number, Houston would have to win to get to 6 victories. As Miami played Houston, this would push their minimum number up to 135. Thus it is mathematically impossible for Houston to finish behind MIA in draft order. A pick of #9 or higher is guaranteed, regardless of Week 17 results.
5 win scenarios:
Arizona - 122 to 129
Washington - 128 to 134
Houston - 128 to 134
Cleveland - 132 to 140
Tampa Bay - 135 to 141
NOTE: It is mathematically impossible for a 5-win Texans team to finish behind Tampa in draft order. This would guarantee a pick of #6 or higher for a 5-win Texans.
OTHER NOTE: It is unlikely that the Texans would go 8-for-10 in strength of schedule matchups with respect to Arizona, which pushes the 3rd pick and Joe Thomas out of reach.
Root for:
KC over Jax (2 game swing over most, 3 game swing vs. San Fran + Clev - besides, it locks Jags out of playoffs)
NE over Ten (1 game swing)
Mia over Ind (1 game swing)
Seattle over Tampa (2 game swing vs. San Fran)
Washington over Giants (improves Washington's record - no SOS impact)
Only applicable if we finish with 5 wins:
Baltimore over Buffalo (3 game swing vs. Cleveland guarantees #5 pick or better)
Special bonus games:
Minnesota over St. Louis (guarantees #8 or higher pick)
San Fran over Denver (guarantees #8 or higher pick - #7 if Minny won earlier)

Minnesota - 117 to 128
