If this "bandaide" can provide 10 or 12 a night, and at least be a threat to score, it's a far cry better than what we have at the moment.
I doubt they are looking at him as long term help, but more something, anything, to at least keep the Spurs in contention for the playoffs.
If we have to depend on Vaughn to play 35 + a night, we are in deep, deep . Tim and Manu can't score enough between them to go with what little is coming off the bench and the rest of the starters to win games. If we have to go through Feb with Vaughn running this team, we are screwed, and the opposition won't even supply the vaseline or the condums.
I suspect we are going to find come Friday morning, the Spurs will have lost 4 in a row, and gone 0 - 3 on the road trip. We are quickly digging a hole we may not be able to climb out of.
We need Tony back ASAP, but not unless he is close to 100%. And right now, noone can say for certainty, when that may be. So, at this point, I would take anyone that could at least help keep the ship afloat.
