I don't think enough to warrant trading him. They should ride out his contract through 2025, which is a reasonable rookie deal of $1.4 Million (including his workout bonus). If he walks in The 2026 Free agency period, they probably get a better comp pick then they would by trading him.
The Packers played far too many season with a crappy, unproved backup QB. Now that they have found a capable one, at a super reasonable salary, why trade him for a middle round pick?
Only way I see Gute trading Willis, is if its for a 1st or 2nd round pick.
