There was an article that the Packers have had a change of philosophy based on three things:
1) UDFAs are getting bigger bonuses. Many of them will earn a larger signing bonus than a 7th round pick. The Packers salary cap issue play into this.
2) Draft depth as a result of COVID years.
3) Gutekunst doesn't use top 30 visits to recruit UDFAs--like Thompson. He uses it to get closer looks at draftable players.
