The point about 3 pointer shots being worth more than 2 pointer shots is generally true. However, in the playoffs, when the going gets tough, usually the jitters set in and the teams hit a lot less 3 pointers than in the regular season. Especially with the season on the line in endgames[1]. Which means: In those cases easy baskets and also mid-range shots (from people who are used to making those) regain their importance. Thus, if you have your playoffs in mind, don't forget to plan for those middies!
