Let's look realistically at playoff chances. I'll (very) optimistically say the Rockets only lose 5 more games, giving them 37 losses. Losses: SA, BOS, @MIA, SA, DAL. Doable, but still pretty optimistic.
To catch New Orleans (37-29) or Memphis (36-29), they would have to lose 8 games. Looking at both of their schedules, it's tough to find 8 losses. I can pick out 6 or so that are probable losses but getting to 8 is stretching it.
Portland (36-27) is interesting because Roy is still coming back from injury, and they've got a pretty tough schedule. They would need 10 losses; I can count 8-9 probable losses left for them.
Denver (37-27) would also need 10 losses. I can find 8 or so probable losses for them.
The bottom line is the Rockets need to shoot for less than 5 losses the rest of the way, and still need lots of help, including passing Phoenix and Utah along the way. It can definitely be done, but for right now, I'm just enjoying watching this team play ball right now.
