No. No way the team is going to trade him without seeing what he can do in training camp and preseason after giving up a pick and putting in the effort of coaching him. It's just common sense.
Anyone who would write such an article obviously has a Dakgenda because there's not even been a whisper from the organization that they want to trade Lance.
The Vikings were mentioned before, but the Chargers? There's absolutely no reason for them to trade for Lance with McMahon now as head coach and Herbert as QB.
