I think we all appreciate what Ninko has done over the years, one of the most consistent and clutch defenders we've had.. If he chooses to retire I wish him well, definitely understandable.
You never know what goes through these player's minds.
Nink is 33. Beyond the torn tricep, god knows what kind of meds hes pumped into his body and physical hell he endured to even get on the field. He might have a physical issue now that he can practice and play with but he'll need to manage all year long.
I'm sure the commitment level BB expects from the players can make a man question if he has what it takes still.
Hes got young bucks who can run all day clawing at his job and here is ole Nink taking 3 hours to get ready for practice and another 2 to take care of his body after practices and games. Then there are the countless hours of daily film study, meetings, etc just to be in a position to even play here....away from his family.
Just doing some reading on him hes been married a few years and has two very small little girls. Im sure hes had his "bell rung" several times and with all the CTE stuff swirling around might also have him wondering if he has it.
Maybe the image of his daughters getting married in 25 years and while they are walking down the isle hes in a wheelchair, using cane or worse has him thinking real hard if he wants to do this.
He has a drop-dead gorgeous wife and healthy, cute children that he wants to enjoy and spend time with. Assuming he's been good with his money and has his health there are worse decisions he can make with the 50+ years remaining with his life.
