Should I stay or should I go. It’s not just a classic tune by the Clash. They are questions college football underclassmen ask themselves every year. Some make the right decision, take their talents to the NFL and succeed. Others get bad advice, leave school early and fail miserably.

Here’s a look at several SEC underclassmen who have reached the “NFL/stay in school” crossroads and have a really tough choice to make by Jan. 15, the deadline for making their decision.

Alabama: Defensive linemen Jonathan Allen and A’Shawn Robinson and Heisman Trophy winner Derrick Henry appear to be NFL locks, but the Crimson Tide has other players who are on the fence. Tight end O.J. Howard, who was probably a better NFL prospect last season, could go in the second or third round. Safety Eddie Jackson, who despite tying for the SEC lead in interceptions (5) and pick-sixes (2), could probably use another year of seasoning. Same goes for Reuben Foster, who could step and replace Reggie Ragland as the leader of Bama’s defense in 2016.

Arkansas: Running backs Alex Collins and Jonathan Williams both figure to be drafted, but neither projects to be higher than a second-rounder. Hunter Henry might be the first tight end selected and looks like a goner. Offensive tackle Denver Kirkland should stay in Fayetteville but probably won’t in light of the fact that the Razorbacks will be rebuilding their offense following the departures of Collins, Williams and senior QB Brandon Allen.

Auburn: Defensive tackle Montravius Adams appears bound for the second or third round. The same can’t be said of defensive end Carl Lawson, who should stick around to prove he can stay healthy and improve his draft stock but probably won’t. Avery Young should stay on the Plains; he might not be one of the first 12 offensive tackles who are selected. Safety Johnathan “Rudy” Ford would also help himself by also sticking around.

Florida: Say goodbye to Vernon Hargreaves, who could be the first cornerback taken in the NFL Draft. The Gators would obviously love to keep starting safeties Marcus Maye and Keanu Neal, but they look like potential second- or third-rounders. Linebacker Jarrad Davis probably should stay in school, but he could go between the third and fifth rounds. Defensive end Alex McCalister is another player who should remain in Gainesville, as is Kelvin Taylor, but the running back’s stock might never be higher than it is now. DeMarcus Robinson looms as a potential headache in the pros, but with so much emphasis on passing in the NFL, it looks like he is running his final college routes.

Georgia: Linebacker Leonard Floyd will be selected in the first or second round. The same can’t be said of safety Quincy Mauger, who would improve his draft stock and boost the Bulldogs with another year in Athens.

LSU: Les Miles would love for Ethan Pocic to stick around, but his size (6-6, 309 pounds) makes him arguably the top center in the draft. Wideout Travin Dural might be best-suited to stay, but the Tigers’ seemingly always muddled QB situation could motivate him to leave. Expect corner Tre’Davious White to be chosen between rounds 1 and 3 and for linebacker Kendall Beckwith to go anywhere from round 3 to 5. Offensive tackle Jerald Hawkins would be wise to stay in Baton Rouge, but probably won’t because he looks like a second- or third-rounder. At 6-4, 264 pounds, Lewis Neal is not the biggest defensive end in the world, but his pass-rushing ability might be hard for NFL teams to pass between the second and fourth round.

Mississippi State: Linebackers Richie Brown and Beniquez Brown have had solid seasons, but staying in Starkville would benefit both. Look for defensive tackle Chris Jones to go in the second or third round. Wideout De’Runnya Wilson could go between the second and fourth rounds, but teammate Fred Ross — arguably the best slot receiver in the country — probably should stay in Starkville, even though senior QB Dak Prescott is a goner.

Missouri: Cornerback Aaron Penton needs more size (5-10, 190) and more college snaps.

Ole Miss: With so many teammates looking like first-rounders — offensive tackle Laremy Tunsil, wide receiver Laquon Treadwell and defensive lineman Robert Nkemdiche — quarterback Chad Kelly might be tempted to try to join them in the NFL. But he could become the top overall prospect in the 2017 class if he gives the Rebels another year.

Despite an injury-plagued 2015, safety Tony Conner looks like and second- or third-rounder but Hugh Freeze has hinted Conner will return. Evan Engram could probably work on his blocking more in college, but like fellow SEC tight ends Henry and Howard, he seems ready for the pros now. Another year in college would definitely help wideout Quincy Adeboyejo.

South Carolina: Look for receiver Pharoh Cooper to go in the second or third round. Linebacker Skai Moore might be looking to join him, but another year in Columbia would serve him well.

Tennessee: Jaylen Reeves-Maybin should lean toward staying in Knoxville, especially since senior teammate and fellow linebacker Curt Maggitt is projected ahead of him as a third- or fourth-rounder. Cornerback Cam Sutton can still work on his coverage skills, but his punt-returning ability could push him into the second or third round.

Texas A&M: Josh Reynolds has pro-like size (6-4, 190) and numbers — 13 TDs catches this season — but he could go anywhere between the fourth and sixth rounds. Nevertheless, the Aggies’ muddled QB situation might push him to the NFL. Offensive tackle Germain Ifedi looks like a second- or third-rounder. Though projected to be third- or fourth-rounder, defensive end Daeshon Hall should stay in College Station to show what he can do without teammate Myles Garrett on the same line. Another year in school wouldn’t hurt safety Justin Evans.
