All of the heart and character in the world won't magically gift you the ability to read defenses, anticipate open receivers, react instinctively, sense the pass rush, and deliver accurate passes. I don't care if he's a Boy Scout. Locker didn't do those things in college. He was very pedestrian. Never cracked 60% completions. Never cracked 7.09 yards per attempt. Had a modest TD to INT ratio by college standards. If he couldn't dominate against amateurs, I don't see any reason to believe that he'll dominate against pros.
I have heard all the excuses about injuries and bad coaching. They mean nothing to me. If you're a great QB, you're supposed to dominate in college. You should be talented enough to thrive even with a poor supporting cast and weak coaching because you're a man playing against boys. Andrew Luck, Sam Bradford, and Aaron Rodgers were doing things in their first season that Locker still can't do after four years of practice. Maybe he just doesn't have it.
Really? He's not Luck, Rodgers, or Bradford. Therefore... what? He has no chance? In other news he's not Manning, Manning, Brees, or Brady. He's likely not even Hasselbeck, Delhomme, or Vince Young. Perhaps a Seneca Wallace. If you don't want to look at the environment that the player was immersed in...well, what kind of analysis is that? He's not your normal prospect. His circumstances aren't exactly average. His team went 0-fer two years ago. They didn't win a game. Zip. Nada. He has a skill set that's worth an investment. He may bloom. Likely not, but the value of potential at the quarterback spot in the NFL is golden. They aren't growing on trees. Teams will do what they have to in order to take a chance on a quarterback.
I wonder, who are you debating with? Yourself? Some invisible anonymous antagonist? I don't see anyone making a great case for Locker's success. I only see people discussing some potential. That's all it takes for a player to get drafted high enough. Top-flight NFL quarterbacks are a rare thing. Teams will invest in the position because they are a rare thing. Perhaps that's the discussion you really want to have? If you were a GM in the NFL...
