"What are failed completions? They are any complete passes that fail to gain enough yardage to count as a successful play based on these guidelines: 45 percent of needed yards on first down, 60 percent on second down, or 100 percent on third/fourth down." Overall Tannehill is good, but it looks worse when it matters the most on 3rd down. Also, the defense is ranked low when it comes to force failed completions. A stat showing the struggles of the LBs, I guess.
