Like MadHatter said, he doesn't seem to fit the mold for Gettleman's defense. Gettleman is looking for bigger, stronger, more powerful guys to come off the line. Keiser is a hybrid pass rusher DE/OLB, that could do wonders on a team with a 34 defense.
Still, with guys like Fua and Armanti on the team, it doesn't make sense to cut Keiser... Not now, at least.
I don't tend to look at who is cut and compare it to guys (at other positions) that I think should be cut.
More meaningful to look within that one postiion to see who is here and who is let go.
I fully expect both Fua and Armanti to be gone by the start of the season.
With the additions of Barner, Ginn, and Adams.....Armanti's potential at ST's in drastically minimized. Not to mention that he was never a real asset as a WR....and we upgraded that with the additions of Hixon and Ginn.
With the drafting of Star and KK, Fua is on the outside looking in.
