I couldn't agree with ESK more. I like Al, I'm sad to see Al go. For a brief period 4-5 years ago Al Harris may have been the best cornerback in football. But that was 4-5 years ago.
Al was never fast. He was a technique guy, which is why he has lasted as long as he has at such a high level, but that's a double-edged sword. When you don't start out fast you also do not have much speed to lose.
Al had also been declining noticeably even before the injury, and that knee injury was absolutely catastrophic. It is extremely unlikely that Al Harris will ever possess the speed to be an effective starting cornerback again.
I always thought he would end up at safety in the Leroy Butler mold. Leroy also never had blazing speed (he always looked more like a small linebacker to me) and Al had the instincts and the run support ability to play the position, but the Packers look to be in good shape there as well.
I also have no doubt that the locker room will not take this well. Everything I here about Al Harris off the field is hugely positive. He's a nice guy, a leader, and a true professional. The Packers on Twitter (Finley, Grant, etc.) were pretty pissed off, and surprised, and I suppose I'm surprised too, but mainly because I didn't think the organization would have the guts to make a move like this.
