Well he and his brother have a similar scouting report.  David Carr went 1st overall in the draft.  That alone would make you consider someone as a potential first rounder.  That David failed will probably hinder Derek's stock.

 

Here's even a source, for the people who like sources:

A player who is a near duplicate of a former consensus No. 1 pick would ordinarily have an advantage on draft day. But GMs face a rare conundrum in this case, unsure of how to grapple with scouting reports on Derek. On one hand, his 50 touchdown passes and only eight interceptions last season suggests that he has all the tools to be a franchise quarterback; Browns coach Mike Pettine calls him the "best natural thrower in the draft." But then there are the issues: Below-average poise and toughness within the pocket; will anticipate pressure and look to protect his frame instead of sitting in 
and delivering the ball.

It's a valid rap. It's also arguably a fixable one. And given Carr's talent, it seems strange that pocket-pressure worries might drop him out of the first round. The problem is that his scouting report echoes what teams said about David -- after it became clear that his career was a bust. "It's an issue," says one NFC scout. "If their makeup is the same, then there is concern."

I think some team could take a flier on him.  And they could either come out looking really good, or come out looking like they wasted a pick.  It's a huge gamble.  Not just because of his brother.  But because while issues can be fixed.  That doesn't mean they will be fixed.  Teams are often desperate for a Quarterback.  So they take one with attributes they like, and figure they can fix the ones they don't.  The ones with the best attributes don't always succeed because their flaws prevent them from doing so.  

 

QB's are a little like houses I think.  Sometimes they need some repair.  If you have someone that's good at their job, you might be able to fix it.  But sometimes the best workers still can't do anything about it, and you just have to build anew.
