Tatum will be fine. I think what Triboy was saying is that Tatum will have good fundamentals like Battier but obviously can score more. I think Tatum will have the craftiness of Pierce giving him the ability to score in various ways but Pierce did have a level of grittiness that allowed him to play defense and grab important rebounds. Tatum may not have that element if his game at the same level as Pierce. Being Paul Pierce is a lot to ask.
My comparable is Reggie Lewis. I see similarities in how he gathers for his shots. It is going to be fun to see how his game plays out.
I agree Reggie Lewis is probably a little better comparison than Pierce at least at this point. Pierce had a power to his game I'm not sure Tatum has. Reggie was a very good defensive player that Jason will need to work on. Reggie was a questionable 3 point shooter though, and I think Jason will be just fine there.
I said it elsewhere but in today's game a better Rudy Gay. Gay has averaged close to 19 PPG for his career, but has become known really as an empty stats guy without much D or passing. Those are 2 areas Tatum really needs to work on. They have similar body types, but I think Tatum will hopefully end up with a more diverse and well balanced game.
