The Seattle Seahawks have been living in a Pete Carroll-less universe for over a season now. He was still part of the organization last season, but on contract alone. He didn't do much except take random phone calls from Geno Smith.
Now, Smith and Carroll are part of the Las Vegas Raiders. So is former Seahawks safety Jamal Adams. Smith is QB1, while Adams is transitioning to inside linebacker, and seemingly doing a pretty good job with it.
Unfortunately, Adams appears injury-prone, so how long he is available for Vegas is anyone's guess. As for Smith, he probably will stay healthy, and the Raiders need him to.
