Baker Mayfield nearly won the Heisman Trophy a season ago, but the remarkable production of Lamar Jackson stifled his climb into true favorite contention.While Jackson has remained productive this season, it hasbeen Mayfields outstanding production and efficiency for Oklahoma that has paved his way to claim the Heisman Wilson Ramos Jersey after finishing in the top five of voting two years in a row.MORE: With just two games left on the schedule and a ma sive lead now built after two must-win games, its Mayfields to lose. How does the rest of the Heisman race look?Just Mi sedJosh Adams, RB, Notre DameJonathan Taylor, RB, WisconsinJ.T. Barrett, QB, Ohio StateJalen Hurts, QB, Alabama5. Khalil Tate, ArizonaWhy hes top five: Since Khalil Tate took over as the Arizona starter, the Wildcats have won five of six games, their only lo s on the road against USC two weeks ago. Tate had his worst pa sing game last week, but he was only needed for 23 plays against Oregon State. His dual-threat production has been reminiscent of Jacksons breakout season two years ago.What he has to show: Despite Tates remarkable production, hes not going to win the Heisman trophy. But if he can put up 400-plus yards of total offense in each of the last two gamesagainst Oregon and Arizona Sate, hell earn an invite to New York.4. Bryce Love, StanfordWhy hes top five: Bryce Love got back to his 100-yard rushing ways against Washington, leading Stanford to an upset victory that puts the Cardinal back in the mix for the Pac-12 title. Love has been in the Heisman discu sion since early in the season, and with 1600-plus rushing yards and 15 rushing touchdowns, his New York Mets Jersey production alone puts him in the mix.What he has to show: Stanfords big win over Washington genuinely put Love back in the Heisman race. With elite running back production on a team that will likely win at least eight games this year, Love has earned an invite to the Heisman ceremony. If he can lead Stanford to a win over Notre Dame to end the season, he may actually have a shot it.HOOVER: 3. Lamar Jackson, LouisvilleWhy hes top five: Lamar Jackson is on pace to be just as a productive and dominant as he was a year ago. But with four lo ses this season (including bad ones to Wake Forest and Boston College), its hard for Jackson to actually earn real Heisman-winning excitement.What he has to show: Voters generally dont want to vote for the previous years Heisman winner again, and Jackson is going to need substantial help to Edwin Diaz Jersey win it this season. Not only will his production need to match or exceed last years (very doable), but hell also need Saquon Barkleys woes to continue, and forMayfield to lose two of the Sooners' next three games.2. Saquon Barkley, Penn StateWhy hes top five:Barkleyhas had just 142 rushing yards combined in his last three games. It hasbeen a tough stretch for the former Heisman favorite, with Penn State losing two along the way and being all but eliminated from the Big Ten title discu sion. Still, Barkleys early-season heroics and clear offensive line struggles should keep him in the mix, should he go off in the last two games. Marcus Stroman Jersey What he has to show: With Nebraska and Maryland still on the schedule, Barkley could easily rush for 250 or more yards combined in the next two games,rea serting himself as a leading Heisman favorite. Its unlikely hell have a chance to win, unle s Mayfield really struggles. But Barkley shouldnt be completely counted out.MORE: 1. Baker Mayfield, OklahomaWhy hes top five:Mayfield played in the Sooners'two most important games of the season back to back the last two weekends, and he couldnt have been more dominant. He pa sed for 931 yards and eight touchdowns, torchingthe Oklahoma State and TCU defenses, the latter of which ranked sixth nationally in yards allowed per game. He has earned the clear-cut top spot in the Heisman standings.What he has to show: Oklahoma plays Kansas this Michael Conforto Jersey coming week, which should be a nice stat-filler for Mayfields end-of-year production. But he still has to get past Will Grier and West Virginia, along with the Big 12 title game, likely against TCU. If Mayfield wins out, the award is his. Even if he stumbles, his lead may be too large for anyone to overcome.
