That's probably about right.
It wouldn't surprise me if one of Griffin and Love is actually dealt, but if we get Horford I expect Love to stay put, meaning we're the only real suitor for Love right now.
Why would Orlando want another guard, though? Harris would be a good wing upgrade for Atlanta, though he wouldn't fill the defensive presence of Carroll on the wings. But I can't really see Orlando wanting yet another guard to cram up their backcourt even more (Teague, Payton, Oladipo, Fournier, Hezonja, Napier, Watson). Realistically, they'd have to get rid of two or more of those guys if they're considering Teague the upgrade and consolidation of guards that they've been wanting.
I'm really afraid that Atlanta, Houston, and Miami are going to get a three-way trade going, though, because they seemingly have a perfect trade set up with their big men:
http://espn.go.com/nba/tradeMachine?tradeId=jtnvbv5For Atlanta, it seems that Howard wants to stay with the Hawks, so they wouldn't have to worry about Horford leaving them in free agency. They'd also probably get much better defensively, but worse offensively, with this trade.
For Miami, it seems that Horford would want to stay in Miami to grow his Hispanic brand, and he'd be a major upgrade for Miami over Whiteside. Also, they pick up Teague to be an upgrade on their failed Dragic pickup. That Miami team could be potentially dangerous in the playoffs.
For Houston, they essentially replace Howard with a younger version of Howard, and they get a point guard that is better suited to play off of Harden, though still not completely ideal.
The only issue would be if the Rockets think that they can retain Whiteside, since no Bird Rights will go with him. If they think they can replace him, this is almost too perfect of a trade for all three teams and the players involved to not consider it, which would suck for the C's.
