The RB's that Tennessee has faced so far; AP, Riddick/Abdullah, Lat Murray/DeAndre Washington/Jalen Richard, Lamar Miller, Jay Ajayi/Damien Williams. None of which are considered to be very good Rb's other than Miller and AP. I chalk AP's bad game against them up to him not playing in preseason and not a lot of snaps and probably a dash of age. Miller the 2nd best RB on that list, had 19 for 82 and 3 catches for 26, not a bad day only thing missing was a TD and those are kind of hit and miss. Also the Oakland RB's combined had a decent day overall as well 22 for 112 and a TD and 3 catches for 19. Again not a bad day.
Crowell is on a hot streak (starting to cool off with week 5 performance), but he's still a top 10 RB this year. But he's a young RB with "fresh" legs who is arguably the best RB that the Titans have faced all year. Or at least the best RB in 2016 that they've faced. I'm confidently playing him at flex this week. He's proven to get goal line carries, and workhorse types of carries so what exactly is there to worry about?
