I take your points, but wins over Chisora and Johnson (even Rogan) are anything better than Price has. Tyson is 24, and 20 fights into his career. Why should he be in a rush to fight seasoned pro's like the Klitschko's. He's moving up the rankings and Cunningham is a decent fight to take. Cunningham is a H/W; whether he is big or small isn't particularly relevant as he is a good boxer. Fair enough if you aren't a fan; but it's a hard argument to take the flip side and back Price and the quality of his opposition.
To use your question - who is Price's best win? Audley Harrison? Matt Skelton? Tony Thompson is a step in the right direction, but you will see that Maloney will not put Price in with anyone who has big power as he knows he has dodgy whiskers.
