Is it a good thing sparring partners have been giving Manny some trouble?

Roach recently said in an interview that despite still looking good in training, some of the sparring partners who are attempting to imitiate Floyd's style have been causing Manny a few problems.

Might this actually be construed as a good thing? How else will he learn to adapt? If he blasted through those guys in sparring, they obviously wouldn't be posing a decent challenge and this could give false confidence going into the fight.

Of course, there's the other side, that if he's having trouble with fighters who are only imitating Floyd, it doesn't bode well for the real thing. So, thoughts? Will it prepare him better if he actually learns a lot from these sparring sessions? Or is it not a good thing?
