Talk to the coaches. They don’t want that.
Coaches are calling plays to the perceived abilities of the players. When Bolin was in the game, they were calling ~30 pass plays per game... with Gio in the game, they're calling ~15 per game.
The OLine has been a problem in pass protection, but they have been showing improvement since the start of the year - they gave Gio more time against PA State than they have against other opponents. The WRs have also been doing a touch better getting separation from their defenders. I just don't think there's confidence in Gio to make the throws, so they aren't calling those plays.
Now, Bolin was given a lot more passing plays, and threw a bunch of picks... but it seems they were still more confident in his arm than Gio's, since they're not letting Gio sling it around at all.
Gio's got grit - he runs the plays, manages the game, reads coverages, and can gain some positive yardage with his legs. What he hasn't really ever shown is the ability to pick a defense apart from the pocket. He's throwing 47% right now... we're not likely to suddenly go "pass heavy" or really even "balanced attack" with him at the helm.
