I think we can all agree on the fact that the Sixers have a very busy offseason ahead. They have holes to fill and puzzle pieces to be put together. One of the Sixers many priorities is signing good free-agents to fill some holes. One of those players that Philadelphia should sign is shooting guard O.J. Mayo. The 76ers are in need of a good shooter, and Mayo is just that. With the Dallas Mavericks this past season, he shot 45 percent from the field and averaged 15.3 PPG, 4.4 APG, and 3.5 RPG. Mayo also shot 41 percent behind the 3-point line and 82 percent from the free-throw line. He has great size, at 6-foot 4 inches and 210 pounds.
