While you are voting for your preferred #10, don't forget about #41: An unusual bit of draft history has seen the Bucks score about as often in the second round as the in first since the turn of this century. Which got me hypothetical-ing...
You can choose from a few more solid second rounders, including Keith Bogans (2003: 2.14), Flip Murray (2002: 2.13), and Jason Hart (2000: 2.20) And of course this doesn't include Mo Williams (2003: 2.18), whom the Bucks grabbed after a short first season in Utah.
The only other first round option is Jason Collier (2000: 1.15). This is considering only players the Bucks actually picked, but if we went back a couple more years, the first rounders would have Dirk Nowitzki (1998: 1.9) while Rafer Alston (1998: 2.10) would become a second round possibility. Alas, this post-1900's only.
