Redbone

 His sire, Rub It In, was just named Man of The Year for the Hereford breed

This is the biggest legged Hereford we have ever laid eyes on

 HEAVY, HEAVY, HEAVY Structured

 Thick and stout, but can still move freely in his joints

 Big legged, bold bladed, stout ribbed, and monster backed

 Redbone is a breed changing creature
