I mean, we can also say that Silva is green, limited, and not very useful outside a certain distance - but I think for the most part people are coming away from his effort very high on his other attributes.
Just saw the fight. Kam has plenty of skill but his physical ability is not there much less world class. He along with Silva can provide decent competition for the contending guys, nothing wrong with that. Had Kam by the slightest of margins, but draw is fair.
