Kellen Moore

Having been a fan of the University of Hawaii Warriors for a very long time, I've been able to see what it takes to be successful with overachievers, as many of Hawaii's prospects tend to be. They're solid and diligent players but maybe because of a giant ocean between them and the continental United States, not everyone is aware of the hard-working talent on the islands.
To a lesser extent but maybe more successfully, the Boise State Broncos are in the same situation. They've never been a part of a BCS conference and the only reason the football team was able to go to BCS bowls was because the Broncos seldom lost. Having watched Hawaii play Boise State over the years, I've learned to admire their ability to perform with a high rate of achievement first hand and have also come to respect the Broncos talent immensely.
Winner
In quarterback Kellen Moore's career for the Broncos, he was 50-3, the most wins ever by a starting quarterback in the NCAA. Also, Moore was a Heisman Trophy finalist (fourth overall in 2010 - see YouTube highlights) so somebody thought he was pretty good. However, when they had the National Football League draft recently, this 6' 197 pound four-year starter for Boise State was not drafted. 253 college football players were drafted but not a single one of the genius' in the NFL felt obliged to use a draft choice on the winningest quarterback in college football history.
It should be noted that another prolific quarterback, Case Keenum of Houston, wasn't drafted either. Keenum signed as a free agent with the Houston Texans. The Detroit Lions signed Moore as a free agent as well (source - WebProNews). Detroit already has a top-notch quarterback in Matthew Stafford as a starter so Moore will be working towards a backup roll.
Lacking
But why have to be signed as a free agent? He didn't have an impressive combine but there are a couple major items the pros don't like about Moore. First off, the left-hander doesn't have a strong arm which is a liability that squashes most college football quarterbacks' chances at the pros - mainly due to the fact in the NFL, the ball has to be zipped into a tiny spot on the field. Secondly, is his height. He's barely 6' feet tall and weighs less than 200 pounds - not a big body at quarterback. That's not ideal because pro quarterbacks take such a beating, plus he will have problems throwing over defensive lines.
Moore threw for 14,667 yards during his career with an offense that wasn't necessarily pass-happy. Plus, he completed about 74% percent of his passes. The son of a coach, he's an intelligent player, who has great command of reading defenses and is a very accurate passer.
The Lions were in need of a third quarterback when veteran backup Drew Stanton left for free agency, so Moore will likely fill that need. Interestingly, six other players on the Boise State Broncos roster were drafted. By the way, Detroit drafted wide receiver Titus Young of Boise State last year and he in-turn, had a good rookie year.
Not a Newton
The NFL, first and foremost is about physical athletic ability. If they could draft quick power forwards with a cannon for an arm as quarterbacks, they would. Think Cam Newton.
Moore doesn't have many of the traits that a modern professional quarterback needs. He's neither quick nor fast or have a gun for an arm - and he's not big. You can look at it any way you want but in the end, NFL teams just don't want to take a chance on a draft choice with all of those liabilities.
I'm very happy Kellen Moore will quit making life miserable for teams like Hawaii in college. Instead, he will compete for a roster spot with the Lions and then wait for a shot. Personally, I can't imagine Moore not making it into the NFL. He has numerous intangibles that the Detroit Lions will have the luxury to more fully examine.
