My defense tallied 24 targets and eight catch alloweds . ....while my opponents qbs threw for 24 completions on 29 attempts . Does that mean 16 catches were completely wide open ? Watching the game would tell a completely different story. Though the catch overs were often.

My DBs allow under 30% of completions (and they don't look like that), but as a team we allow 63%.
It looks like this stat is broken.
