The Cavs suffered through another difficult season in 2011-12, but last year's No. 1 overall pick Irving proved he was worth the investment.
Fellow second-year player Tristan Thompson looks to make a big leap this coming season, and has flashed his defensive ability and magnificent offensive rebounding.
What the Cavs sorely lack is another legitimate scoring threat outside of Irving, with the likely departure of pending free agent Antawn Jamison.
Thompson is still too raw to contribute offensively, and the Cavs are losing nearly all sources of offense from last season's team.
The defense was not much better, so with two picks in the first and second rounds, the Cavs should have a new look roster this coming season.
Here are the top five rookie pairings in the first round that would give Irving and Co. a huge lift and help the Cavs compete for a playoff spot in the Eastern Conference.
