But Lawrence is as advertised. Of course Lawrence could be a bust. But That's the NFL life of evaluating and drafting of a potential franchise QB..
Lawrence is as advertised at the college level, but the Cowboy's concern is the pro level, and that's what the poster you responded to was talking about. The point he was making is we don't know about the pro level.
And yes, that is life with evaluating and drafting, and part of that is understanding the risk of letting a proven high quality player go in favor of a prospect that is highly thought of, but also unproven.
In the end I think the poster was simply saying that drafting Lawrence isn't the sure way to improve some make it out to be. And, realistically, the evaluation you mentioned could lead the Cowboys to that thinking as well. Or they could decide Lawrence is the better way to go. Either choice would have some foundation.
Not that I think the Cowboys will end up with the first overall pick ...
