Even though several NFL teams desperately need to select a quarterback in the 2014 NFL Draft, this class of signal callers may currently be slipping farther and farther from becoming first-round picks. The draft is very similar to the stock market as the value of players can rise and fall depending on certain pieces of information. Quarterback Teddy Bridgewater was once considered the front-runner as the first-overall pick in the draft, but his average Pro Day performance and poor private workouts could have him falling as far as the third or fourth round. Johnny Manziel had one of the most impressive showcases out of all his counterparts, but character concerns and durability issues are still trumping his performance. When Andrew Luck was drafted, he had very few risks associated with him and has proven that he was a great selection. The quarterbacks from this class, however, are not as much of a sure thing as Luck was. Mock drafts and predictions will constantly change from now until the draft, but pass-rusher Jadeveon Clowney now appears to be the favorite target of the Houston Texans. It makes sense for the Texans to pick Clowney, as he is widely considered the most talented player in the draft, but Houston could also land a top quarterback prospect with the first pick in the second round. If Manziel can slip past the 11th pick of the Tennessee Titans, he would have a great shot of falling to the Texans at the start of the next round. The Cleveland Browns do hold the 26th-overall pick, but the organization cannot afford to take a risk at the quarterback position. If teams are still scared away from selecting a quarterback early, the Texans will have the opportunity to draft two of the most explosive playmakers from the entire draft. We all will have to wait until draft day to see what unfolds, but things are about to get very interesting in Houston. Jack Delaney is a fantasy football writer for Rantsports.com.
