Definitely helps. It's no secret that Iowa is great at evaluating talent, it's just been unlucky at landing some of the higher rated players. Early signing allows Iowa to lock those guys down, as well as a establish the bulk of their class early so they can be more selective in the later period, as they have done last year and this year. It also allows Iowa to take more serious looks at "late-bloomers" such as Kaevon Merriweather last year, who otherwise might have gone unnoticed by most programs.
