Going on 10 days past Toine's official release and still not even one confirmed inkling of a rumor that anyone is interested in Walker as a pick-up.
I think that is a very telling sign.
A telling sign that I could be taking a very long vacation from this board. *gulp*

Of course he could be just taking his time over the holidays wading through all the offers he has received from across the NBA and around the world. 
Nah. Personally(and all this is just speculation on my part....heck, this post of yours is also speculation but whatever...), I think Walker is TRYING DESPERATELY to latch on to a Playoff-Team, IMO.
If he cannot, then I think he seriously considers going to a Non-Playoff team to "just play basketball". He won't retire at 32. Even though he has more money than all of us put together.....

But all that said, though....Just because there is no confirmed rumor of any team wanting to sign him doesn't mean that there aren't teams that wouldn't mind giving him a shot as a 10th men/bench player to give them 10-12 minutes...Also, remember that the Basketball World these days don't really pay much attention to the NON-Stars in the league. Walker is officially an afterthought. (but don't tell him that.

)
