I don't think she fits the all-around USA OH mold. There would have to be massive improvements and adjustments to her game.
The USA doesn't need her to be that anyways (they have plenty on the team or in the pipeline) They need the OOS weapon that they don't have. I hope playing behind Boskovic can help her with that. (playing both OH/Opp for Ecza)
By all around OH I mean balanced OH and not defensive OH. MBH was terrible receiver before but she gradually improved. If JT can do that then her place as OH in the American team is mostly secured. She can hit balls in system and out of system already. I just hope she doesnt turn out like Brankica (no offense to her though).
