I'll take Cov over Maark; Saric over Zach.
Covington is a high level 2-way player.
Saric does a lot of little things that help a team.
Maark is a nice player, but I see him as more of a high plateau guy than someone who keeps getting better. Seems like he already has a mature game, so I don't anticipate a high ceiling.
Zach is a defensive mess, erratic shooter, overpaid, injury history.
Dunn = defensive effort, shooting woes. A backup PG.
When the first Butler trade was made, Zach was an erratic gimp looking for a big payday, Dunn a mess, the pick an unknown.
It was an infusion of (risky) yute. CHI lucky they hit on the pick. Maark taken 7th one slot ahead of Franc.
