So given the choice of running your players into the ground, potentially increasing their already lengthy injury list, or trusting some of the squad (and note that he has over 34 players at his disposal) and resting some players, you'd go with the former rather then the latter?
I mean the most ridiculous thing about all this is Newcastle have actually used the most players so far out of anyone this season, yet haven't rotated in the past 5 games, so to me this shows that a) Newcastle DO have the squad to cope and b) Howe simply does not trust anyone else bar his favorite 11.
He has 10 reported injuries, level with Sheffield United, Chelsea and Crystal Palace, one more than United and Spurs.
