The move now puts 22 players signed to the Rockets. That's more than you're allowed to have, if you were wondering. Of those 22, 11 are forwards. So yeah, they've got a little bit of a roster issue. 

Specifically, Delfino seems to be a complication on the wing behind rookie Jeremy Lamb and Kevin Martin. That would lead you to think the Rockets are considering a trade, but really, when aren't the Rockets considering a trade? With Dwight Howard off the market, the big fish is gone. So whatever they do will have to either be really inventive of fairly minor. 

One thing's certain, they keep adding assets baffle most of us and the end game, if there is one, is not clear at all.
