Lawrence is being paid an average of about $41M for the 5 years from 2024 to 2028. I think he's an upgrade over Smith, but not a $15M per season upgrade. Admittedly I don't know what salary Smith will command after 2025, (assuming his team option is picked up). I didn't like that the 1st 4 years of Lawrence's contract were effectively guaranteed, but I guess anyone trading for him would only be picking up 3 years now. I'd understand acquiring him, but I wouldn't give up anything significant to do so. Hard to see the Jaguars agreeing to trade him for less than a 1st and 2nd.
Not that it'll happen as Lawrence has a no-trade clause and he seems to be happy where he is.
