The college football regular season is more than halfway done, and the Heisman Trophy discussion is just heating up as it gets to November. When looking for Heisman candidates, it's important to remember the impact the player has on his team, where his team sits, and of course his numbers. This is a top-five list for the 2015 Heisman award heading into 10.

1.    LSU Running Back Leonard Fournette - It seems fairly clear that Fournette is at the top of everyone's list, and within the first couple weeks of the season he had already been claimed the frontrunner. The sophomore running back rips through tackles like paper bags and already has 1,352 rushing yards in seven games this season. Fournette is averaging 7.7 yards per carry and has 15 touchdowns. The 6-foot-1, 230-pound running back is the best player in college football right now. The LSU Tigers are undefeated this season, and being the best player on an SEC-dominant team only helps Fournette's chances, even though he doesn't need it.

2.    TCU Quarterback Trevone Boykin - The senior quarterback is picking up where he left off last season. Boykin had an incredible season as a junior for the Horned Frogs and is only improving his senior year. Boykin has 2,539 passing yards with 25 touchdown passes. The TCU quarterback is a dual threat, as he has rushed for 440 yards this season and scored five touchdowns with his feet. Many felt TCU was robbed when it was held out of the College Football Playoff last year, but Boykin hasn't let any of that affect his play this season. The Horned Frogs are 7-0, and if they finish the regular season undefeated with a win over Baylor, it will be impossible to keep them out. Boykin will continue to be a top name mentioned in the Heisman conversation, as he is quarterbacking arguably the best team in the country.

3.    Baylor Wide Receiver Corey Coleman - The Bears wide receiver broke a school record on Saturday, reaching 31 career total touchdowns, and still has plenty of time to add more. The junior receiver has exploded this season for Baylor's offense. Coleman has 18 touchdowns this season with 962 receiving yards. The Bears will be without their starting quarterback Seth Russell the rest of the season, due to a neck injury. Baylor will play freshman quarterback Jarrett Stidham down the stretch, and if Coleman continues to put up big numbers with a freshman quarterback, expect him to earn even more praise this season. Baylor's last game of the season is against TCU, and the winner will likely have a candidate at the Heisman ceremony. The last time a wide receiver won the Heisman was Desmond Howard in 1991, and Coleman will need to continue to have monster numbers if he wants an invitation.

4.     Stanford Running Back Christian McCaffrey - The sophomore running back has been a huge reason the Cardinal have won six straight games. McCaffrey has 953 rushing yards this season with six touchdowns. He has also caught 21 passes for 284 yards with two touchdowns. McCaffrey leads the nation in all-purpose yards, averaging 259.7 yards per game. The son of former NFL All-Pro Ed McCaffrey is clearly making his own name this season. Stanford is the only team unbeaten in the Pac-12 conference, and if it finishes as Pac-12 champs, McCaffrey will easily be a Heisman trophy candidate.

5.    Ohio State Running Back Ezekiel Elliott- Despite constant changes at the quarterback position this season, Elliott has been the one constant for the Buckeyes offense. The junior running back has rushed for 1,130 yards and 13 touchdowns. Ohio State is undefeated and is looking to win the Big Ten for a second consecutive year. Elliott has rushed for more than 100 yards in 13 consecutive games and is clearly the Buckeyes' top offensive weapon. At 6-foot-1, 225 pounds, Elliott is has speed and power and consistently displays his talent every time he steps on a field. Ohio State is looking to repeat as National Champions, and Elliott is looking to carry the Buckeyes there.
