If the Cavs let Clark, Gee, and Varejao go they will be at around 35 million with rookies and cap holds. If by some chance they got Deng locked up at around 11 million (for year 1) that puts them at 46/47 million, which would mean they would have room for a near max contract. I do think that Lebron and Deng could play together with James at the 4 and couple them with Irving, Waiters, Thompson, Zeller, Jack and with Bennett, Karasev, and rookies as potential I think they would have a pretty darn competitive team. They would need a center unless Zeller takes a big leap, but I think they could find at least respectable centers from the veteran minimum crowd or rookies (and maybe Varejao comes back on a minimum type deal).
