I still think against most teams the starting lineup will be Walker, Brown, Hayward, Tatum, Kanter. Those are the 5 best players on the team (well Smart may be better than Kanter, but he isn't starting over him) and they should start the 5 best players on most nights. There are probably teams where you need a bigger guy out there initially so as to not wear Tatum down as much, but there aren't that many of them.
