Johnson, who is away from the team in a contract dispute, told ESPN's Michael Smith that he'd like $30 million to $40 million guaranteed.
"So would I," Fisher said. "You know he's under contract right now."
Beyond that, the Tennessee Titans coach didn't have much to say about Johnson's continued absence from the team's organized team activities, which are wrapping up this week.
"I'm not going into my relationship with him, whether I've talked with him or not" Fisher said. "This is something I feel will eventually get worked out."
Fisher said with Johnson out the Titans are fine with four running backs (and two fullbacks) right now, but that they are always looking.
If Johnson holds out at the start of training camp, the Titans could seek an extra body to help spread out reps and allow for rest when someone is injured.
And if the contract dispute looks like it could encroach on the season, they'd likely look closely at backs who hit the market as teams trim rosters.
