I totally agree.
Horses, when first introduced to jumping, should be lunged over small jumps or free jumped in an arena over small jumps. You want the horse to gain confidence over the jumps without the worry of carrying a rider.
Confidence is a big big big factor in jumping, the horse has to figure out how to move its legs to jump and gain confidence that it can successfully do it, just as people have to work at something to gain confidence.
Start with very small jumps to lunge/free jump her over, and under saddle I would do a lot of trotting poles and cavaletti. Once she goes over the poles/cavaletti confidently under saddle, and is jumping the small jumps as if they are nothing (confidently) then I would start jumping TINY jumps under saddle until she feels comfortable going over them and is relaxed (Important!) over them.
I think any horse can jump, if you start them correctly and slowly.
Good luck! :)
