First, you can't remove a game lol..... And you can't ignore his hands history going back to college.
Second, you have to look at targets. TY had 120 targets, while Funch had 79. That's less than 2/3rds of TY's. I'd also note that TY was a victim of too many forced balls when he was in double coverage. That won't happen nearly as much this year. Funch was I believe 3rd or 4th in targets for Carolina, and was rarely doubled.
I do agree Funchess can be good in our system, but that's if they limit him to the routes he's good at (like the ones the Colts published). I also think that Luck is good enough, and smart enough, to throw balls away from his body (he's better catching at eye level or higher, or outside of core). Regardless, I'd bet a lot of money he doesn't hit his incentive (unless we have some serious injuries at WR).
