Seriously people.
Marbury was off for a year. A YEAR.
And he has spent basically his entire career as a starter. If you expected him to come off a 1 year time off, have him come off the bench for 5-10 minutes and light it up for 20 points, then you seriously need to reconsider your mentality.
There are some players that can come off the bench and hit shot after shot right away. We call those shooters 3 point sharp shooters. Not point guards.
