The 2016 NFL season didn’t exactly go according to plan for New England Patriots rookie DB Cyrus Jones.

The former Alabama standout was designated as inactive for all of the Patriots’ postseason wins, including the thrilling come-from-behind victory in Super Bowl LI.

Jones took to Instagram on Sunday to express his disappointment in himself for his rough season, calling it “by far one of the most challenging times in my life”:

Reflecting back on my rookie season, this was by far one of the most challenging times in my life. I experienced a lot of pain, disappointment, embarrassment and overall dissatisfaction with myself. But through this time, I learned many lessons that as a man I can say I truly needed to learn..”Failure is another opportunity to begin again more intelligently” and the things I went through this year made me better and wiser. Regardless, I was blessed to be apart of something far greater than myself! I experienced the ultimate measure of success in this game we play…and did it with an even greater group of men and I’ll never take that for granted. I was quickly reminded how much love and respect I have for this sport and also how much it means to so many people. So with that being said #patsnation , in 2017, 24 will be back and ready to work for the best fans in football! #revenge #godstimingnotmine #seeyallinyear2

“I experienced a lot of pain, disappointment, embarrassment and overall dissatisfaction with myself,” he added.

Playing in 10 games as a defensive back, Jones recorded seven tackles. In 10 games on special teams, he returned 11 punts for 43 yards and also amassed 180 yards on eight kickoff returns.

After playing a key role at Alabama during his Crimson Tide career, taking a step back as a rookie was tough for Jones.

However, a new season brings new opportunities and he’ll likely have every chance to make an impact on both defense and special teams as the Pats look to defend their Super Bowl title in 2017.
