Ludeke has a good 1st class record and would no doubt be a good coach, but I see him as the same type of coach as HM, only the latter being better.
Not that I am on the calls for a replacement for AC as of yet (however - I will definitely feel like that next time we lose I DON'T CARE WHO WE PLAY), but I would ideally want HM back, even if that is the farthest-fetched dream, even further than Jake's reappointment.
It should be said that last week's performance by the team on the pitch cannot really be put on the coach (ill-discipline, unforced errors, etc.). Faf De Klerk was woeful compared to his own standards. Elton.. (bleh). We are literally our own enemy on the field, because whenever we somehow win back the ball or gain even a little momentum, we let ourselves down by committing unforced errors. Something I'm sure every coach dies a silent death in the box when he sees it happening.
However, from a game management sense and defensive point of view, it is pretty clear these players are not WELL EQUIPPED to handle the challenges presented to them on match-days and that can solely be aligned to the coaches.
A realistic view would be to replace his assistants. Johann Van Graan looks more like he should be the physio. I don't even recall ever seeing Mzwandile Stick, but I am picturing him wearing dreadlocks. Their expertise are NOWHERE on the field, and as such they need the boot. And in turn I would make Johann Ackerman the forwards coach and perhaps his (tactical) assistant - Swys De Bruin - the backline coach.
I've listened to a few interviews of Ackerman and I have a feeling he has something up his sleeve for next season.
