Niners Nation on Garrett Celek

From the article

Tight end Garrett Celek's 2016 experience under Chip Kelly's simplified offense illustrates how simplification can benefit players. Celek praised the efficiency of Kelly's hand-signal playcalling system, noting that reduced verbiage made plays easier to remember and execute: "In the past we had a lot of delay-of-games because either we're not getting the play in time from upstairs or it's just taking the quarterback too long to read the whole play out. Where now, it's a lot quicker. We have hand signals, so you can't have 15 words through hand signals, stuff like that. It's got to be boom, boom, boom. So when you got less verbiage, it's easier to remember. It's kind of genius." This historical example supports the potential benefits of Raheem Morris's simplified 49ers defense.
