I guess the most frustrating part to this is he is a very good safety inside the box, and for arguments sake is one of the teams best tacklers and pass rushers.

Pass coverage is just something he does not excel in.

I was a fan of Mike Jenkins when came out of college but the years in Dallas wasn't good to him and then he would come to a team were he's playing for the same coach I don't know if it's a good fit. I'll pass

Harper is arguably above average in pass coverage when it comes to flats, which is what his type of a SS is expected to be - he is not a FS or a CB.

At no point did I say he was a free safety or corner. I agree, he does play the flats well. Moving laterally from the line of scrimmage to the flats and out, I think Harper is very good in pass coverage. But once he moves out of that zone he becomes a liability.

Yeah, I didn't mean to say that you were implying that he was a FS or a CB, just that his pass coverage skills should be evaluated as those of an in-the-box SS, not of a FS or a CB.

While that does make him a liability when it comes to dropping back into coverage, I find it hard to be really harsh on him because of that since you wouldn't expect a DT to drop back to cover a TE. I know that may not be the best comparison, but I think it still gets the point across that certain positions can't be expected to cover for other positions' lapses or mistakes in defensive playcalling.

An in-the-box SS is somewhat limited in his role when it comes to pass defense, but if the defensive scheme calls for a player of that type, then I do think they earn their keep quite nicely - as Harper has in the past.
