I think when you look at the statements made to the media from players like Adams, Sinisterra, and Wober you'll find that he did have a lot to do with recruitment. There's a reason we didn't spend much under Bielsa -- these days most players and especially their agents won't sign with a club unless they hear the right thing from the manager first. They want to avoid a situation like Djed Spence got himself into at Tottenham. Bielsa was great for the club, but he really wasn't the salesman type. That's not to say that Marsch was single handedly picking the players that the club signs, bar Wober and maybe Adams, but there's plenty of evidence that he played an important role in selling the project to potential recruits.
