I haven't seen the announcement of the summer league schedules yet but I confirmed today that the teams will be in both Las Vegas and Utah for Summer Leagues. When they first signed up for Vegas there was an assumption they would be at both, but then there were rumors they would be in Vegas only.
Kevin Durant will be on TV. This probably guarantees us 2 televised Sonics games a week for the next month if you have NBATV. Great for the young guys and great for us fans.
Kudos to the organization for spending the money. There is a considerable cost to taking a squad to summer league and their reasoning for canceling Utah would have been budgetary. They're taking a lot of heat for being penny pinchers and this is a nice investment.
