Draftscout.com has Mayfield listed at 6-002/220, 4.64/40, that height, if accurate upon measurement at the combine would make Mayfield 5/8" taller than RW, also note he's a little heavier and slightly slower than RW. IMO- Accuracy + durability + Grit + the "IT" = a likely Rd-2/3 area target for the Seahawks I would hope as that pick could extend RW's career once a talented backup QB w/starter potential like Mayfield is obtained as the QB of the future.
