Having Rebecca Lobo in the studio means a greater commitment to true "analysis." Lobo is one of the only WCBB commentators who will talk about the Xs and Os - where a down screen occurs, running off the ball, setting an elevator screen at the top of the key, etc. These are things the average basketball fan does not know. They are the subtle nuances of the game that has made Lobo's commentary so great.
Carolyn Peck basically says the same thing. She says, "When you talk about [insert team name], it all starts with [star player]. [Star player] can do it all - scoring, rebounding, passing. [Star player] is so versatile, and it will be very difficult for [opposing team] to stop her." Seriously. That is a basic summary of the in-studio analysis she contributes.
In recent years, Peck has added things like "[Team name] plays more of an up-tempo style" and "[Team name] likes to run but needs to learn how to execute in the halfcourt."
Having Lobo in the studio means there is a "Jay Bilas type" who brings incredible substantive analysis to the proceedings. It makes for a much more informative broadcast, especially for casual fans of the women's game. Using someone known for her Xs and Os analysis is a statement that ESPN is not relying on someone who was a fired coach who some perceive as good looking; it is using one of the best analysts (if not, the best women's basketball analyst) as the main component of the broadcast.
Plus, people underrate Lobo's dry sense of humor. During a WNBA broadcast on Oxygen in 2004, Beth Mowins and Lobo were calling a game together. Mowins had to do a blurb about "Nice Package," Oxygen's new home improvement show. Lobo's first quip after the blurb was, "Oxygen...the euphemism network." One of the funniest moments I have experienced watching a women's basketball game...
