I am talking throughout the season and what I said applies to every team.For some teams it is. Other teams have gone the whole season basically playing seven or eight and have had no problem at all.
But if you are going to use the injury thing then you can't say this Pitt team only had nine. They had 12. They only got down to nine AFTER the injuries, not before. So you could say that Pitt did have quality bench guys in case injuries did occur. Because injuries did occur.
It isn’t as important at this time of the year because guys are getting rest in between games and watching video on their opponents. You can get by with a good 7 man rotation in March, but you are walking a fine line in case of foul trouble or an injury.
