I don't know much about Barron's background but he basically got a double double the last 7 games of the season and seemed pretty active in the couple games I saw. If continued playing like that he wouldn't be a bad backup center.
I also think Barron is someone worth looking at. I mean sure his time with the Knicks is a small sample to draw any conclusion about him, but still averaging double-double in the games that he played with them is quiet commendable.
And if he continues to do that then I think he would make a great backup center for us.
So if we can't get Shaq than I would rather have us get Barron instead of Kwame Brown.
