Wiggins, Embid, Parker, Exum, Gordon, Smart, Randle were all talked about A LOT the year before and the year after they were drafted. At the time, it was considered the deepest draft class since 2003, which included Lebron, Wade, Bosh, and Carmelo.
Listening to Bill Simmon's podcast the last couple weeks, and it seems like they are talking about Jabari at least 3 times/week. Outside of PG13 (Playoff P?), Kawhi, and Lebron, I would guess Jabari is the most talked about "free-agent" this off-season.
Plus, Parker was averaging 20/game the year of his big injury. That gets you on everybody's radar.
