It’s been very rare that any of our subs have had an impact this season, because they don’t get long enough on the pitch. Hirst has never scored buckets of goals himself, he creates chances for others whereas Delap is generally wasteful.
Substitutions can be made earlier, but there must be a reason why McKenna has left it later than usual to bring players on this season. It’s most likely because he doesn’t trust in those players to influence a match at this level.
Hirst hasn’t been able to create chances for others because top division defenders are able to nullify his strengths. My fear is that he’s not the same player he was before his knee issues. At 25, he’s yet to hit his prime years and he can clearly do a job in the Championship. Hopefully he can overcome the injury issues and lead the line next season - because it’s looking increasingly likely we’ll be without Delap.
