Duos are great to have on a football team because opponents cannot key in on just one player. Coaches can get more creative with their schemes and play-calling. Also, having multiple talented players is never a bad thing in the first place.
Many potential dynamic duos may arise from recruits in this cycle. Kentucky offensive coordinator Neal Brown has a future quarterback-to-receiver combo which should score many points in his offense. Clemson can say the same thing with two of its commitments.
Alabama has a pair of defensive studs who should team up to hurt SEC offenses. Finally, Texas A&M may see two of its defensive backs make a great tandem.
The Hurricanes have scored commitments from two great offensive tackle prospects. Having a pair of bookend blockers to protect 2013 signee Kevin Olsen will help the Miami passing game.
McDermott, who is 6'6" and 301 pounds, is the higher-rated of the two. However, Darling is a 6'5" 314-pounder who is no slouch in the trenches.
Olsen should have a clean pocket to work in with this duo of tackles blocking for him.
Scout.com rates both Barker and Snodgrass as 4-star recruits. They will be coming to Kentucky to play in a wide open spread offense coordinated by Neal Brown.
Barker, who is 6'4" and 200 pounds, has good arm strength and deceptive running ability. He should develop great chemistry with the 6'2", 175-pound speedy Snodgrass, who hails from Ohio.
Wildcat fans can expect some fireworks and big plays from this duo.
The Seminoles have been looking for linebackers the last two recruiting cycles. Although Pugh may become a defensive end, he is capable of forming a great outside linebacker duo with Purifoy.
Pugh, who is 6'4" and 225 pounds, has good quickness and is a solid pass-rusher. He is not great in coverage, but has potential to be an adequate zone defender.
Purifoy, who is 6'2" and 234 pounds, has a great ability to quickly read his keys, process information and make tackles in a flash. He is a stout linebacker who can play inside or on the flanks.
Having two outside linebackers who have contrasting styles that play off each other's strengths will work well at Florida State.
Watson makes good decisions and is a quarterback who is not going to just wildly chuck deep balls all game to assure himself a highlight.
He has the arm strength to fire balls downfield, but the 6'3" passer understands that making first downs is what keeps his offense on the field.
Kitt, who is 6'0" and 200 pounds, is a quicker-than-fast athlete who has a similar skill set to Rams receiver Austin Pettis. With Kitt not being a deep-speed type of receiver, the pair could be on track to connect for many intermediate completions.
Even when Johnny Manziel leaves, the Aggies will still be able to score a lot of points because of the greatness of their offensive scheme.
They will be ahead in many games, which means their opponents will be forced to throw the football more. Therefore, Kevin Sumlin must make sure he has a strong secondary.
Harvey and Sumner-Gardner are two of the best safeties in the country. Harvey, who is 5'10" and 170 pounds, is among the most instinctive players seen on tape. Sumner-Gardner, who is 6'1" and 197 pounds, is quick to fill run alleys and plays with good range.
Having these two defending the seams in College Station will help the Aggies close out many games.
Although this duo will face a tough climb up the depth chart, they will form a rock-solid tandem in the middle for Alabama.
Hamilton, who is 6'1" and 240 pounds, hits like a freight train. Ball-carriers feel his force when he meets them at the point of attack, and it doesn't help their case that he has great short-area quickness.
Whitley is rarely fooled by misdirection in the box. The 6'2" 220-pounder has outstanding ball-location skills and vision. He is a good tackler and flashes good blitz ability.
SEC offenses will be forced to attack the edges of 'Bama's defense after this duo establishes itself.
