Dave - your assertion re his call up is ridiculous. Haslem DID get hurt, no call up. They signed stackhouse when they needed to fill a spot earlier, now they signed dampier.
You just mentioned two players who play different positions than Mason. This is like saying the Yankees have a stud SS when the LF and C go down he doesn't get called up.
Players who have aspirations of playing pro ball in the NBA go a different path then guys who are just content with making a living overseas.
There are so many different leagues overseas and if you want to play in the NBA you're going to have to go through Euroleague. Mason wouldn't get PT there especially being an American and young (no insult to him even Brandon Jennings didn't get time in a lesser league). So he could possibly sit there or he plays in another league but then is held up by contracts if he wants to come back to the states.
The NBA DL offers easy exposure to NBA teams with easy accessibility. Why do you think Scottie Reynolds, Patrick Ewing Jr., and a lot of other american born players are playing the D-League now? They could easily cash in overseas too but they are chasing a dream.
YOU SAID:
"Because assuming the Heat have any more injuries he gets the call up first and foremost."
You were not specific. In fact, if Jerry Stackhouse doesn't play his position either, then Mase is only coming in for James Jones....or if LeBron gets so hurt he gets put on injured list.
You act like he's so close, but refuse to lay it out how it really is.
Mase is a long shot to make the NBA anytime soon. Best of luck to him - I hope he gets smart and gets paid soon.
