i live in dallas and don't have league pass so i didnt get to see the games where splitter got major minutes, but i did see him for a short stint against Boston and in the short time he was on the floor he was completely out of position on defense and got beat bad and then got rejected by Delonte West when he was going up for a dunk.
i'm not saying those plays are indicative of who he is or who he is going to be, but I think those are 2 key examples of why he is not starting next to Timmy right now.
Bonner may not be the best defender out there but he is a decent team defender and rarely out of position on that end of the floor. He also may not be a force in the middle, but as much as everyone wants to laugh at it, Bonner does spread the floor and is a legit threat. Unfortunately, he is struggling with his shot right now, and has been famous for disappearing in the playoffs.
I think Splitter will be a big part of the team next year, I still don't believe he is/has been ready for the role that most of us wanted him to have this year.
PS the Bonner isn't the reason we are losing, poor team defense and NO ONE besides the big 3 contributing are the bigger concerns
