It should be noted that he only has a $1M guarantee up until 1/10, so he is still relatively easy to waive in order to sign somebody else. Obviously you can waive either of Kornet or Jackson, but I don't see that same guarantee on Jackson's contract and it's possible every dollar saved will be important because of the tax.
Anyway, yeah, I was preaching this all summer and was sure he'd be gone before even his $1M guarantee kicked in. I was wrong. Don't want to be mean - Luke is a great locker room guy for sure - but it was a perplexing signing when it happened (we signed him almost immediately, like he was a prized FA) and we can see nothing has changed. Luckily Vonleh, Griffin, and even Kabengele should be able to provide productive minutes at the 5.
