TD is predictable and so is Shaq. However, both are unstoppable when they are healthy. I think teams have adjusted over the last few years. Duncan has been one the best for the last few years.
Having said that, I do think we are going to see a better Duncan after the all star break. I think he improved tremondously in the 2 outings (given his recent form) against the Cavaliers and Sixers. I think he will average 22 ppg, 12 rpg, 3 asstpg and 2.3 bpg for the remaining 32 games.
