I’d be very curious to know if there’s a difference between the offensive rebounding rate on FT’s in general vs. the offensive rebounding rate on the front end of a 1 and 1. This is just anecdotal observation, but it seems like the team missing the front end almost never gets that rebound.
Also, a missed front end is one of the easiest stops a defense will ever get. A turnover may be forced or unforced. To regain possession with a missed front end, all a team had to do was foul someone and grab the rebound on a missed FT.
