Cavs bench struggles

After watching almost all Cavs games so far this season, I've seen how terrible the bench is. I wanted to brainstorm some ideas on how to make it better, here is that list.

First, here is the second team that keeps giving away Cavaliers victories:

PG: Donald Sloan
SG: Gibson
SF: C.J. Miles/Omri Casspi
PF: Jon Leuer/Luke Walton
C: Samardo Samuels

1) The obvious thing is to have either Kyrie or Varejao on the floor with Daniel Gibson and the scrubs. Maybe rest Kyrie with about four or five minutes left in the first, put him back in, in the second quarter, while you give AV a five minute rest or vice versa. You could do this with quarters three and four also. Especially when Tyler Zeller comes back, this second team may not be half bad.
With this lineup, there is no doubt points can be scored:

PG: Kyrie Irving
SG: Gibson
SF: Miles
PF: Leuer
C: Zeller

Alternatively, if you let Varejao rest in the first:

PG: Sloan
SG: Gibson
SF: Miles
PF: Varejao
C: Zeller

Not as ideal as the first, but it could work if Miles ever comes around.

2) This is along the same lines as the first, but with different players. With this option, you would play Kyrie the entire first quarter as Dion Waiters would get pulled with about three or four minutes remaining in quarter one. Gibson would come in for him, and stay in during Kyrie's rest time.

PG: Gibson
SG: Waiters
SF: Miles
PF: Leuer
C: Zeller

Here I would play Gibson at point guard, specifically for defensive purposes. Watching him try to defend Joe Johnson the other night wasn't pretty. So we'll let Waiters handle the bigger guys. The offense however would go through Waiters. He's a better ball handler/playmaker than Gibson.

3) Run the offense through the bigs. Here I would sit Tristan Thompson and Varejao for a bit in the first. This way, you have a respectable amount of defense on the court, plus TT and AV can go up and get the rebound on the inevitable misses. I'd like to see a lot of pick-and-rolls with Varejao with this team.

PG: Sloan
SG: Gibson
SF: Miles
PF: Thompson
C: Varejao

4) Sign free-agents! There are plenty out there that frankly it's a surprise they don't have teams. The Cavs are so far below the salary cap that they could probably sign four or five players. It won't hurt the rebuilding effort to give some of these guys one or two-year deals. Admittedly, this one is more for fun, but here's what the bench could look like.

PG: Delonte West/Gilbert Arenas
SG: Gibson
SF:  Miles/Mickael Pietrus
PF: Eddy Curry
C: Zeller

An overhaul that big wouldn't be welcome I don't think. But an acquisition like West may pay dividends. We all know he has talent, offer him a contract where if he screws up, he's done. It would be Chris Grant's terms, make it low risk and high reward. West would instantly make the bench better.
