I suppose in a way it is similar to Warnock only naming outfield substitutes. It is a risk, but a calculated one, and in the biggest game when Warnock was caught out without a goalkeeper we still won.
I think if anything I am surprised that Adkins has used up all his subs so early in every league game so far. If on the odd occasion he needed to make more or more radical changes to turn a game in our favour then fair enough, but getting all his subs on long before the final ten minutes seems like clockwork as much as previous managers refusing to change anything until an hour has passed and throwing someone on to rescue a game in the final two minutes.
Perhaps Flynn and Peterborough is just too fresh in the memory!
