The following is just my initial thoughts on how we are going to approach free agency, and what I think are moves we could be looking at. bear in mind, that I haven't a very large knowledge of free agency, cap space and anything else of the sort so some of the scenarios might be completely fucking wrong and impossible.
The PG position doesn't really worry me too much after watching Delly in the post season. Kyrie and LeBron are going to be handling the ball and playmaking for 90% of our time, so it doesn't strike me as a very big problem, if we are healthy.
What we do need, imo is someone who can create his own shot to come off the bench, however. It absolutely killed us that we didn't have a proper offensive option to check in and make something happen with the ball in his hands, and getting a perimeter player able to do that would do wonders for us. The obvious name is of course Wade but the question is what his price tag is going to look like. I think we have other holes that need to be filled in our roster and it would be a shame to throw the majority of our resources after one player. The other issue I have with going after Wade is his age. I realize Wade being over 30 isn't as big of a deal, if he comes off the bench and would more or less be designated the leader role when the big 3 isn't in the game, but I still don't like the idea of throwing significant resources after a guy who probably isn't going to be a major part of our team in 2-3 years.
Outside of Wade we have guys like Monta Ellis (player option), Jamal Crawford (Team Option), Wesley Matthews might be available for cheap considering his injury etc. obviously none of them is a perfect match. they all have deficiencies that we will have to work around, but going by what I consider to be our biggest needs and who we could get for the most reasonable price would probably be Crawford. He's able to knock down the open jumper, has great handles, and is good at finding the open man, so you can rely on him to play PG in a pinch. On the other hand he is a black hole on defense and not as young as you'd ideally want him to be.
The other hole in our Line-up is at center, IMO. We are pretty set at PF with Love, TT and maybe even 'Bron in spurts but we desperately need someone to shoulder the load defensively at the 5, outside of Mozgov, Andy and TT (who ideally shouldn't even have to play there unless we're trotting out a small ball line-up). I think Mozgov has proven that he is more than capable of starting on a contender, so what I'd be looking for wouldn't necessarily be an upgrade but rather some of the same in a smaller dose, at a smaller price. I have hard time finding any candidates in FA that fit that description though. There are a lot of great centers available but none of them really seem all that realistic. there's Koufus I guess.... so that's a thing.
the last thing we need, and what I think we will be addressing through the draft is perimeter Defense and length. posters have gone on at length on here about possible draft picks and I really haven't been studying this draft class all that closely but based on what I've read if Rondae-Hollis Jefferson is available when we get our go, you take him and don't look back. If, however the Cavs decide to pick up a center during the draft instead of going after one in FA, I could see us pursuing a guy like Aminu if he decides to opt out of his contract.
