I'd like to see Joey Dorsey added in the summer.
I think he'd be a really effective garbage man power forward (elite rebounder, solid defender) alongside a highly skilled offensive center (like Garnett).
I love the idea of those two, Garnett and Dorsey, together in a quick lineup. I think they'd complement each other very well defensively (in a quick lineup). Joey as the burly physical defensive PF and Garnett with his quickness, length and intelligence. Their ability to play tough physical defense, force low percentage shots, force turnovers, dominate the boards (Dorsey is a terrific rebounder) and create extra possessions would be very useful.
