Not using the TPE or making any additions at the deadline would be extremely idiotic. Go all-in. And even if the guy seems "redundant", that's kind of the point. If someone gets hurt or needs rest (or is in foul trouble), they can come in and play some minutes. If you aren't letting guys like Walsh, Banton, etc. get many minutes then it probably means they won't get any in the postseason. Get a depth piece that's a bit more experienced and can fill a role. Center is my obvious choice but even a combo-forward that's big can help out and provide depth (or some injury insurance)
