What to keep an eye on when the Cavs and Bucks match up tonight at the Q:

1. Which new addition has made a bigger impact for the Bucks, new coach Scott Skiles or trade acquisition Richard Jefferson?

The Bucks added two new faces this offseason, bringing in former Bulls coach Scott Skiles as a defensive-minded head coach, and trading Yi Jianlian to the New Jersey Nets for Richard Jefferson on draft day. The jury is still out on both in this young season.

The Bucks brought in Skiles to assert his defense-first attitude on a team that finished worst in defensive efficiency last year, giving up 112.8 points per 100 possessions. Through the first seven games of the season, the Bucks are "only" allowing 97.9 points per game, 19th in the league, and giving up 102.9 points per 100 possessions, good for 14th overall. Unfortunately for Skiles, the Bucks have had problems defensively over the last three games, giving up 103 points per game to the Wizards, Celtics and Suns last week. Skiles and his schemes will be put to the test by the Cavaliers' new, more active offense.

As for Jefferson, he has been solid, dropping in 18.3 points per game while adding 5.1 rebounds and 3.7 assists. Jefferson is a solid player, but he's not quite an All-Star, and it's hard to tell what the Bucks were doing in acquiring Jefferson but trading away Mo Williams for a bag of balls a few months later. With Williams, the Bucks might have had enough offense in the backcourt to keep things interesting, but there's just no reason to expect that a Jefferson and Michael Redd combination can amount to anything more than a .500 team.

2. Will Michael Redd play?

Redd has missed the last three games with an ankle injury, and is questionable for tonight's game. Redd was averaging 21.3 points per game in the Bucks' first four games, and the Bucks were 2-2 when he went down. Last season Redd beat up on the Cavaliers, with 25.5 points, 6.5 assists and 4.3 rebounds per game, and he hit this mean 3-pointer to give the Bucks one of their three wins over the Cavs last year.

With Redd, the Bucks are a much bigger threat when they come into the Q tonight. Without Redd, I don't see how the Bucks are going to score enough points to keep up.

3. How will Mo Williams match up with his Bucks' replacement, Ramon Sessions?

The Cavaliers were able to acquire Mo Williams from the Bucks during the summer in exchange for Joe Smith and Damon Jones. It was a very good trade for the Cavaliers, but one of the reasons the Bucks were able to part with Williams for so little was because they had Sessions waiting in the wings. Sessions is off to a hot start for Milwaukee, averaging 17.2 points, 6.2 assists and 3.6 rebounds per game, numbers that are eerily similar to what Williams averaged last year (17.2 points, 6.3 assists and 3.5 rebounds).

Williams may be looking for a little revenge against his old team, and Sessions will be looking to prove the Bucks made the right choice in turning the point guard duties over to him. Should be fun to watch.

Go Cavs.
