I'm going to go out on a limb and say that Musah is the most replaceable field player on the pitch, wasting the most individual talent on the team.
Fear is the our better players won't return to their previous form coming back from injury.
If Ponch is going to stick with a 4-2-3-1, then the middle five have to be Pulisic, Reyna, Weah Adams and McKennie. I'm not seeing anything from this latest group. Aaronson isn't showing enough quality to be anything more than a late defensive replacement. The centerback situation is dire. Way too many opponents gashing though the middle in the defensive third.
