On 3rd or 4th and 2 or less the sneak worked 84% of the time.
A pass on 6 that scenario worked like 63% of the time
A handoff worked like 64% of the time.
I forget the exact numbers but it was something like that. Sneak is the call every time. Especially when it's a yard or less.
I also saw a stat a few years ago about Matthew Stafford. He was 16-16 (100%) on QB sneaks at that time.
