Want a name of the type of dude you are looking for in a backup/third point guard? How about Leandro Barbosa. He impacted this series even in a situation without injury.
What was needed from the back-uppoint guard, as a hedge against Irving being injured (a predictable possibility), was ball-handling, scoring, passing; i.e. an offensive skill set. The GM obviously knew this, but for whatever reason, could not complete the transaction.
No hate here, he did everything else he needed to do. Ultimately, with hind sight, he probably would have rather had Will Bynum than Kendrick Perkins. But c'est la vie.
Again, Delly is just not the type of guy needed for this role, but he does have a role on the team with his hustle and defense.
I like Mo Gotti.
