I think that team is probably worse than our team.
You lose #16, Tyrus, Gordon,and Hinrich for Kaman #28 (we could chase the same FAs anyway).
I don't think Kaman and getting Deng back remotely makes up for losing Tyrus, Gordon, and Hinrich. It may not be the worst situation going forward because Hinrich, Gordon, and Tyrus combined have a much larger kap hit than Kaman, so you can reallocate some of the salary space later, but as a straight "how will the team play" perspective I think that team is far worse.
It also is far more injury prone relying on both Deng and Kaman to stay healthy rather htan Gordon/Hinrich who have much better track records (gordon's never missed significant time, and Hinrich had a fluke injury that's not recurrent while Deng/Kaman both have injury issues that are likely to recur).
Of course you don't need to dump Hinrich, and you might lose Gordon anyway, so it's probably not entirely a fair comparison. Realistically, Kaman is just replacing Tyrus + expiring deal. I think whether he outperforms Tyrus next year is up for grabs.
Tyrus actually had a higher PER than Kaman last year though Kaman only played in 31 games, so it may not be a fair comparison. Go back a year though and look at this:

Look at the per 36 minute stats, the scoring rate is similar, the overall efficiency is similar. Kaman was a much better rebounder (important for us though since we really need that), but otherwise they were fairly similar. That's Kaman 2 years ago though when healthy. You don't know if you'll get that next year or not, and Tyrus is definitely at a point in his career where we could still see significant improvements whereas Kaman probably is what he is at this point.
I'm not sure that you gain much on the court with Kaman vs Tyrus. I haven't watched enough of Kaman to say how good he is subjectively away from the stats. I haven't looked at his defensive ability and how good his positional defense, help defense, and man defense are. He may bring a lot more than the statcard, but then again he may not.
