Four-star prep forward Tyler Cook is among the players who signed with Iowa and coach Fran McCaffery on Wednesday.
Cook joins Iowa high school stars Ryan Kriener, Cordell Pemsl and Jordan Bohannon in the Hawkeyes latest class.
Cook, who is 6-foot-8, is considered among the nation's top power forwards.
Kriener is a 6-foot-9 forward out of Spirit Lake, Iowa.
Pemsl, from Dubuque Wahlert, is also a forward who should help Iowa compensate for losing the likes of Jarrod Uthoff and Adam Woodbury in the post following this season.
Bohannon is a 6-foot-1 guard from Linn-Mar High who led his team in rebounding last season.
The Hawkeyes open play Friday by hosting Gardner-Webb.
