The odds are against a GM picking up guys who stick and guys who start. That's why the better GMs are so valuable.
It's just that picking a QB has repercussions well beyond the particular draft pick used. Entire systems are often built around a QB, including the types of RBs and WRs. So when you pick one, start him for a while and it is a failed experiment, it usually sets the franchise back some years as everything (often including the HC) have to be reset.
Never liked the Trubisky pick; never thought he was a starting caliber NFL QB. He intrigued because he was that "mobile" QB. The guy who could "also" do it with his legs. Problem is, the odds are against them because they tend to get injured. They begin fast because they can use those legs but once the injuries start the team starts to work with them to stay in the pocket and stop running so much; and it affects their entire game.
Now that Nagy is trying to make him more of a pocket QB, it is exposing his poor mechanics and his lack of ability to see the field. He's young and perhaps he can progress and overcome it. But up to this point, not looking good.
