Every January, talented juniors have a big decision to make: stay and play for their senior season or declare early for the NFL Draft.

Staying for another season can help a player build on experience, skill and range. Or it can open up the player to injury or lead simply to an unsuccessful season that damages draft stock.

Here’s a look at some of the Tide talent that decided to finish out their senior years and may have left themselves open to some regrets:

LB TIM WILLIAMS

Williams hasn’t wasted a single second of his time at Alabama, and he made the somewhat surprising decision to put in another season for Tide head coach Nick Saban.

Williams could have easily gone in the first round of the 2016 NFL Draft despite the fact that he wasn’t even a full-time starter last season. He racked up some monster numbers, including 10.5 sacks, finishing ninth in the country, and 12.5 tackles for loss.

In 2016, Williams will undoubtedly be a starter for the Tide. In addition to the increase in playing time, he will gain even more experience, improve as a player and move his draft stock into the top five for 2017, according to Mel Kiper and other experts.

It wouldn’t have been a bad decision for Williams to enter the 2016 draft, but he definitely made a better decision by staying in Tuscaloosa for his senior season.

Verdict: No regrets

DL JONATHAN ALLEN

Allen sat and watched as some of his closest friends started the next chapter in their lives. Former Tide stars A’Shawn Robinson, Jarran Reed and Derrick Henry all saw their dreams come true when they were drafted into the NFL earlier this year.

He could have joined them. And he likely would have been a first-round selection himself. Last season, Williams led the team with 12 sacks, 14.5 tackles for loss and 2 forced fumbles.

Unfortunately for Williams, he missed the spring game and much of spring practices with a shoulder injury. He will likely be back strong in the fall and continue leading this Alabama team, and he will probably still be drafted in the first round. But he must be wondering if he should have followed Robinson’s lead and entered the draft when he had the chance.

Verdict: Having regrets

TE O.J. HOWARD

Howard worked hard but stayed under the radar in his first two seasons with the Tide. Then in 2015, he racked up 38 receptions for 602 yards and 2 TDs. Of those, 8 receptions, 267 yards and both TDs came in the two postseason games.

Suddenly, his draft stock rocketed. But Howard chose to stay at Alabama for his senior season in order to become even better. He definitely made the right decision.

He might have been a hot commodity after his postseason performance, but NFL teams knew little else about him. And with an upcoming season guaranteed to give him more experience and exposure, his draft stock will continue to increase.

Verdict: No regrets

LB REUBEN FOSTER

Alabama fans breathed a sigh of relief when Foster chose to stay in Tuscaloosa for his senior season. After all, the Tide lost former star LB Reggie Ragland and former defensive coordinator Kirby Smart in a single offseason, leaving Foster in charge of leading the defense.

Foster easily could have gone in the first round. He was a defensive beast in 2015, racking up 73 tackles, 2 sacks and 9 pass breakups.

Like some of the other players already mentioned, Foster has not yet reached his peak, and the additional year of experience will help rather than hurt his NFL future. In fact, he’s looking to become an even better linebacker than Ragland ever was in his time at Tuscaloosa.

Verdict: No regrets

PK ADAM GRIFFITH

Griffith currently holds the No. 2 and No. 3 spots with the most PATs in a single season for Alabama, making 53 of 54 in 2014 and making 62 of 62 in 2015. He also finished the season 23 of 32 on field goal attempts, including two field goals made from over 50 yards. Then, he executed a successful onside kick — with the help of CB Marlon Humphrey — that arguably won the national championship game against Clemson.

But he has officially peaked. Griffith has seen both his best season and his worst season in his time at Alabama, and it’s not likely to get any better for him.

After barely scraping by in 2014, he should have taken full advantage of his performance in 2015 and entered the draft.

Verdict: Having regrets

DB EDDIE JACKSON

Jackson has been racking up the preseason honors with First-Team All-SEC and the watch lists for the Jim Thorpe Award and the Walter Camp Award. That’s no surprise when you consider how he performed in 2015.

In his first season at safety — after making the move from cornerback — Jackson collected 6 interceptions for 230 yards and 2 TDs, as well as 28 tackles. His performance earned him First-Team All-SEC and defensive MVP in the national championship.

Jackson is hot, and he hasn’t reached his full potential yet. Another year in Tuscaloosa will likely give him a much stronger draft stock for 2017.

Verdict: No regrets
