Well, Clifford has a 7'6 wingspan. There are not a lot of guys that are like him with his athleticism and wingspan. Also, I never said that Sherrell and Clifford were the same type of player. All I said was that we don't need to bring in another big if Sears doesn't return. We will replace Sears with likely another ball handler. Sherrell is very capable, especially as a backup, and has potential to be a star. When you bring in Sherrell to give Cliff a rest, you have a different dynamic and get to play more 5 out.
Also, Sherrell isn't like Stevenson size wise. He is more solid and can actually defend the post a bit. Really the only real similarities is that they can step out and shoot the 3.
