This doesn't seem like much of a question.
Fans might not have seen Glenn Robinson much last year - he played just over 150 minutes with the 76ers - so you might not know much about him. How can you make an assessment on someone who played so little? By providing something of a scouting report.
Glenn Robinson is a big wing suited for the modern NBA. Standing at 6'7", he's got enough size to defend most shooting guards and forwards. Typically, that's what scouts look for when assessing defense - size and the ability to defend multiple players.
