The perfect free agent is a player who is still young, is a proven performer with no injury history or character concerns, and who is not overpriced. Good luck finding many of those unicorns in free agency.
The combine opens up next week, so soon we will be talking about who performed well there and how the combine changes perceptions of these players. The Packers will have plenty of people at the combine to observe and finalize their draft board.
What is undeniable is that free agency starts before the draft. While General Manager Gutekunst won't know which players will be available when he is on the clock at the draft, or whether he will be able to move up or down in any particular round, he should know the positions of strength and depth in the draft.
