I understand the criticisms of Whalen--since I'm one of those who made them. I also appreciate her tremendous talent to penetrate--and to finish. She brings a different kind of energy than does Sue.
It may be unfair (I'm prepared to accept that assessment) to "blame" her for the significant change of pace and movement when the second team is in. It may be more than Whalen's style. For example, I really, really, really admire EDD's game, but even she, while moving very well, needs at least a bit more of the set play than do the starters. Although Stewie may not deserve to be among the first off the bench, I suspect that, if she were, the pace and movement would pretty much remain as with the starters.
It's not a bad thing that the pace changes. While the second team seems to slow things down, they also therefore take time off the clock and the change of style challenges the defense. Just that the first team, with Sue and Dee running things, reminds me of a certain college team's offense that I so admire.
