As already answered, Rule 5 was cancelled this year, but to add to that, Kevin Smith wasn't exposed to the rule 5 draft. It's only players who aren't on the 40 man roster (which he was) and who have a certain amount of playing time (depending on if they were a high school, or college draftee, or IFA).
Basically the only people who are ever exposed in the rule 5 are players that the vast majority of fans have never heard of, unless they're the types who dig through prospect lists. (We did have 2 guys who would have been exposed this season who were at least interesting...)
