Lydon played two years at Syracuse as sort of a tweener. They used him at both the SF and PF positions. I personally think he's better suited for the PF position. He was a very good 3 pt shooter at Syracuse averaging 40% from the three both years he was there. He was a decent to good rebounder and maybe a slightly above average athlete. I always thought he was a bit overweight at Syracuse. He was drafted by Utah if memory serves and traded to Denver. I don't think he got much of a chance to play at Denver, so the jury is still out.
I always thought that if he could get into NBA shape, he could be a player. He certainly has the skills to play in the NBA. He's certainly worth taking a small gamble on since he's still young, and has good size at 6'9.5" and around a 7 ft wingspan. I would expect the Kings to sign Holmes now that their above the cap.
