You just might question his intelligence for giving one of his team's division rivals, a club coming off a 10-win playoff season, such bulletin-board material a couple weeks before training camp opens.
During an interview with the NFL Network, Jennings openly questioned the Lions' on- and off-the-field maturity, and who can blame him?
After all, this is the team that was repeatedly penalized in big games last season, including
Ndamukong Suh's well-publicized stomp on Thanksgiving Day against the Packers.
It's also the same team that leads the NFL in offseason arrests with six since late January, and the team with a receiver (receiver Titus Young) who reportedly sucker-punched a teammate during a workout several weeks ago.
Jennings asks a legitimate question.
"Can they maintain their composure, both on the field and off the field?" he said. "They're a very talented team, but they have struggles on the field containing their composure, and definitely, the things we've heard of, them being in the media with off-the-field problems and off-the-field issues.
"Can they be a professional ball club for 16, 17, 18 solid weeks throughout the regular season?"
Those questions won't be answered for a few months, until the Lions get into some hotly contested match-ups with the division title on the line.
Games like Nov. 18 against the Packers at Ford Field, and on Dec. 9 in Green Bay.
It's one thing when the media criticizes something. It's another thing when your coaches harp on it.
But when the arch-rival, a former Super Bowl champion, calls you out?
That's when it should really hit home that several players need to get their emotions and actions under control.
Otherwise, as Jennings' suggests, an apparent up-and-coming team is only going to go so far.
