I absolutely think it factored into the decision. If they thought Lutz would return to 2018-19 regular season form AND had 2-3 years left on his deal, they probably keep him. If they have even minor concerns about the former knowing he has 1 year left on his deal AND we can get something (even if it's minimal) in return, then yeah, that all certainly factors in.
One thing that is odd about this preseason. There have now been THREE trades for kickers, something that almost never happened before (CLE traded for Hopkins and TEN traded for Folk).
