In addition to what I had posted earlier, it gives me peace of mind to know that Tony is another Wing we can throw at Kobe.
Even once Pierce and Marquis comes back, TA will still get some minutes, I believe. And against certain teams (like LA) he can certainly be a big help.
Of course he won't stop Kobe completely, but he can help slow him down.
Just thinking about having Pierce, TA, Marquis and Ray Ray to throw at Kobe makes me sleep better. That's just my take.
