my interpretation of his comments are that the Dolphins have a good matchup this week and he figured Crowder would be the starting MLB this week so would be worth a start this week, but he's not too confident in him given how little he has produced the past couple weeks.
however, it now looks like Thomas is expected to play this week...so I think you have to bump Crowder down a lot.
The funny thing is, when Zach was playing a few weeks ago, Crowder was getting 10 tackles per game. Then when Zach got hurt, Crowder was getting around 4 tackles per game. Maybe Crowder moved from OLB to MLB when Zach got hurt and did worse than when he was playing OLB, which is where he will be moving back too now that Zach is back in the lineup.
