If I had to grade their FA so far, I'd give it a B. I like the DFS signing as a 3&D depth piece as he can still match up well vs most wings + he's a pretty good team defender and he can be a reliable outlet for guys like KD, Sengun, Amen, and FVV.
However, unless it's a trade piece, I don't understand the Capela signing, they already have Adams as a backup big, I don't understand it for Capela either, the Rockets don't have an elite dynamic PnR creator, and I would go somewhere where I can still get good minutes like, ironically the Lakers
