Very good moves.
Teague is a better defender and distributor than Jennings and apparently wants to be here.

Teague - Mayo - Ridnour ?? provides a far better balanced backcourt than what we had with Jennings / Ellis.

Bucks are trying to become the Pacers, and given the number of teams in the league that are trying to really tank, these might end up being pretty darn good moves.

The key to the whole thing is Giannis actually developing as they hope he will. It is a low risk gamble where they picked him, but if he should become the Greek Freak that would be the equivalent of a high lottery pick in 2014. Difference is he is with the Bucks a year early. If he does not develop as hoped, well that's what you get in the middle of the NBA first round.

Getting rid of the malcontents (Jennings / Ellis / Luc / some backups) and bringing in more team focused guys will turn this team into a .500 or better club next season. Tanking doesn't even guarantee a top 10 pick next season.
