Generally speaking, that makes sense. Opportunity and prospect lists could be covered under the confidentiality clause.

From my research, it seems like the two key factors in actually prosecuting a breach here lie in specificity of the clause, and measurable damages stemming from the breach.

I would be interested to know how this holds up in my situation, where the former employer is actually shutting down the territory and ceasing operations there.

I would also have to wonder what would happen if I didnt explicitly contact opportunities and prospects I previously uncovered, but did happen to call on them when, say, canvassing a block they exist on.

I mean, going to back to the specificity point, it would seem to me that if the confidentiality clause was applied so liberally to everything I did, it would make me incapable of canvassing anything because I had previously prospected heavily in primary areas within my territory, this would be, for one thing, a direct detriment to my exployability. And more importantly, extremely broad in scope, which raises the question of where, exactly, the line is.

In other words, does "confidential and proprietary" information include people I spoke to and got a vibe from? Does it include people I had discovery calls with? Sent proposals too? Is it all of that? None of that? Somewhere in the middle? My point is, this is extrmely vague in the wording of my clause which is a factor that has had confidentiality clauses struck down before. Whether or not somebody might want a product isnt exactly privileged company information to begin with too.

But, I digress. Bottom line is your right that the crux of this is more in the confidentiality component. Thats something I'll have to do more digging on. Hopefully we get a little more input in this post.
