Why are people getting fired up about this? I think we really have to look at this from a developmental standpoint. While it's easy to sit there and say "we could use Walker's athleticism" and "Hudson deserves to be on an NBA roster" how practically is this going to work? Paul played 35 minutes last night, Ray played 34, and Daniels played 25. That isn't going to change. Similarly, Rondo played 32 minutes and House played 14. Simply put, unless Walker can beat out Daniels and Hudson can beat out House, they're not going to play any minutes here but garbage minutes, and is that really worth it?
Furthermore, while some people may have high opinions of these guys, they have proven absolutely nothing in the NBA thus far. They certainly don't deserve any special accommodations, no matter how old they are.
Sometimes it's just best to let young guys play. Look what the Sox did with Buccholtz. He pitched his no-hitter then was in Triple A the next year because there wasn't a rotation spot for him.
Let them go down, work on their games, and if the opportunity arises later for them to play, they'll be all the more ready.
