I get where you’re coming from - more effective coaching and instructions should certainly be the first order of business.
As SpoonTon said, the motivation for having an extra centre back and central midfielder in front of them would, in theory, help with the issues you’ve highlighted. The hope would be another body at the back capable of getting a head on the ball at set pieces, then an extra man in the middle to press and make us harder to play through. It would then be up to Ballantyne and Okike to have the legs to get up the park on the break, with a striker and O’Halloran ahead.
All well and good in theory, but no guarantee at all it would make enough of a difference to start picking up points. It shouldn’t be an overly complicated change to make, though that will very much depend on the coaching and game management from the dugout.
Would hope for a change of some sort in any case…
