Bradley left the NFC champions ahead of the 2013 season to take up the head coach's post at the Jacksonville Jaguars.
He told the Jaguars' website: "I am excited for those guys up there, but my love now is with Jacksonville.
"Me being excited for them, I don't want anything to take away from what we're doing here, but I was with those guys for three years. You do grow close to them, and you see guys grow through it. I'm excited for them.
"To say I don't care about those guys, I would be lying. I want them to do well. We saw it growing. It's exactly the style we saw coming together."
The Seahawks face the Denver Broncos at the MetLife Stadium tomorrow.
