That's the thing, Algeria has only been to the AFCON final 3 times, winning twice. Compare that to Cameroon (7-time finalist, 5-time winners) or Nigeria (7-time finalists, 3-time winners). Cameroon has been to 7 WCs, Nigeria 6. 2014 was the best showing from Algeria when they reached the R16. Prior to that, they never made it out the 1st round.
There's still the case of performance in the Olympics.
I probably rank em like this
Tier 1A - Cameroon, Nigeria
Tier 1B - Egypt, Ghana
Tier 2 - CIV, Morocco, Tunisia, Algeria
People were saying taking the under 2.5 was guaranteed money
