If people are going to criticize Gettleman, then they should criticize every general manager in the NFL because every GM does this when a player with small value/importance suffers a season-ending injury but is a player they still would like to keep.
The player almost always makes it through waivers and onto that teams IR. Unfortunately Patriots appeared to like Gaffney a lot in spite of his injury.
As a huge Gettleman supporter even I have to admit this was a pretty bad mistake on his part. Espescially considering the same thing happened to the Giants when he was on their staff.
Teams waive injured players every day, during preseason there are at least 10 moves like these every day around the league. I guess for some of you is a smarter idea to keep him on the roster and cut a healthy player you want on final cuts. Very bright.
