Chad Ford just published his annual column ranking draft prospects by tier, which is always an informative read. For those not familiar, the tiers are based on polling of NBA GMs. For the first time ever, not a single player made Tier 1 (sure-fire star like Griffin, Durrant, and Davis) OR Tier 2 (potential All-Stars - last year MKG, Beal, Robinson and Barnes). This year, six guys fell in Tier 3: Bennett, Len, McLemore, Noel, Oladipo, and Porter Jr. Tier 4 is Adams, Burke, Carter Williams, KCP, McCollum, and Zeller. Ford says Tier 4 guys mid-first round guys, but in this weak draft, they'll be mid- to late-lottery picks.
