Lutz's percentage has gone down each of the last three years he's played, finishing a disappointing 74.2% last year. Even if he has a rebound season, that could make assessing his value for a new contract a challenge, and also riskier than would be ideal. I'm with you that I can live with whatever decision is made - Grupe is unproven and not without question marks - but from a roster management standpoint, it could make sense to get something for Lutz while they can, audition Grupe (or another kicker) this season, and see where they are going into next year.
