So a few good games against some of the weaker teams in the league(yes Cleve was missing their top players) and you want to rush and sign him to the extension? The spurs should wait until near (another month) the end of the season, see how he looks then, then open up talks.
Manu will not be playing at this top form that we have seen the last few games for the next 2 or even 3 years which he will want, count on it.
You sign players for what they will give back in the future not what they have done in the past.
A verbal agreement between Manu and the Spurs needs to be considered regarding his future international play. If he decides to play the spurs need to take that into account in what they will offer him- which should be less than if he forgoes playing in the international tournamnets. The spurs need to make an incentive for manu to skip international play.
The spurs need a plan to shore up the frontline with some talent and without it even signing back Manu will make no difference.
