The NFL Scouting Combine workouts on Sunday were the most important in regards to the April draft, as the quarterbacks invited to the combine had the chance to workout for scouts and executives, including Geno Smith, Tyler Bray and EJ Manuel.

The number one pick in the draft was likely to be a quarterback until the Kansas City Chiefs appeared to make a trade for San Francisco 49ers star Alex Smith, opening things up for the Chiefs and the other teams at the top. Geno Smith was likely to be the number on pick, but that will likely shift to one of the top rated offensive linemen, including Luke Joeckel from Texas A&M.

The quarterbacks on Sunday all had solid workouts, including Tyler Bray, Matt Scott, EJ Manuel and Mike Glennon, who all helped improve their draft stocks with how they performed in drills. Scott was able to impress the scouts with his athleticism in his drills and he was able to place in the top in every category in drills, including the three-cone drill, in which he topped all quarterbacks.

Here is a look at some of the top quarterbacks and how their workouts went on Sunday at the Combine in Indianapolis.

Tyler Bray, Tennessee

Bray is one of the underclassmen to come into the NFL draft and he did himself a few favors at the combine when it comes to his draft stock, as he looked much bigger and stronger than his time at Tennessee, weighing 232 pounds and looking strong as he threw the ball in workouts. At 6-foot-6 he has a favorable frame for NFL scouts and his ball had zip on it and accuracy as he worked out on the field and if a team likes him they could snag him at the end of the first round or in the earlier rounds.

Mike Glennon, NC State

Glennon is considered to be one of the best prospects at the combine and in the draft and he proved why on Sunday by showing off his strong arm down the field. He proved to be less accurate than other quarterbacks in the draft, but he is tall and big at 6-foot-7 and some NFL teams could take that as enough to draft him even without the crisp accuracy. He was faster than Bray and Matt Scott at the 40 after running a 4.94 and also impressed in his vertical jump with 26.5 inches.

Geno Smith, West Virginia

Smith proved in his workouts why he is considered the top quarterback prospect in the draft. He ran a 4.50 40-yard dash and was also impressive in the vertical jump at 33.5 inches despite his short stature at 6-foor-2. Had the Chiefs not made the reported trade of Alex Smith, it is likely that this Smith would be the top selection in the draft come April. He made all the throws he was asked to make at the combine and the Jaguars and other teams at the top of the draft will take notice of his speed and he could fit the mold of a Robert griffin or Russell Wilson in the NFL.
