but Costa has actually shown some good technical skills in Romero fight

[AimedWithV]

costa is probably on a very short list on power for mw's with good but not spectacular technique

What he showed in Romero fight,both in wrestling an striking department - I'd say it's closer to "spectacular" than "good"

Costa probably walks around at like 250lb. I think he is going to be way too big and strong for Isreal.

Israel has fought at Heavyweight, giving up 10kgs

and never lost, knocking people out.

The gap between precision is huge, the gap between power is not as huge
Izzy has a big advantage here and hence is the favourite.
