I don't exactly see how this is a crime against humanity. I also don't know what you expected to happen in the off-season.
#1 McCourty
#2 and #3 - Harmon and Ryan (or draftee)
#4 and #5: two of Wilson, Ebner, Chung, Davis or draftee (and no, we don't expect to see the #4 safety playing much on defense, unless there are two injuries). I recall bringing in Ihedigbo as a special teamer. Folks thought he was awful. He was, as a starter. However, he was brought in as a special teamer, as Chung was. Personally, I would rather have Chung playing than Wilson or Ebner.
=======================
And yes, there is still the possibility of bringing back Gregory, now that he has found out his worth on the open market. Gregory is certainly a reasonable backup.
=======================
We will all have our fights over the draft board. Of course, no one will be happy unless we draft a stud all-pro in the 1st round at SS, DE, TE, OG AND LB. Of course, the draft doesn't work that way.
So, yeah, we need a top draftee at safety, and I would be fine with a first rounder. I just don't expect us to draft a safety in the first three rounds.
I think it is a crime against humanity.
None of them offer starting capacity worth a damn, even though Harmon warrants a longer look and could have a nice second year leap. If Belichick feels as though Harmon has already earned the starting spot opposite of McCourty, that's not only a major roll of the dice for a couple reasons, but it also leaves no one but special teamers behind him.
Belichick passed on a lot of vets that were relatively cheap in free agency, so I think the plan is to add a higher draft pick myself. As you said, the possibility exists of adding Logan Ryan to the mix as well. Obviously there's a plan, so it's likely one of the two--if not both options.
I'd be happy with not only giving Ryan a shot at safety, but also bringing in a top 1-4 round safety again. This time with better results. I think that could change things dramatically.
As far as Patrick Chung goes, he could be nothing more than camp fodder, or he could make it as a ST only player. Let's just hope we don't see him on the field in too many real defensive situations.
