"I'm quoting what other draft experts and insiders who have met him and his coaches are saying"
The only guys in people you mention that matter are the coaches. The rest of them are parroting what they've been told. With respect to the coaches, let me ask you this: Ever had a boss who didn't like you? What do you think they told third parties about you when discussing your performance?
Did you think Aikman was a poor quarterback because he didn't like or get along with Barry Switzer? And what do you think Switzer would have said about Aikman to others if Aikman hadn't already established himself as one of the premier quarterbacks in the league?
"
If you are contradicting that you need to have similar level of evidence not some lollipops and rainbows take just because we drafted him"
I have no idea what you're saying here.
"Where is the evidence that he took to coaching, was a good practice player and was disciplined ?"
There are dozens of guys each year who do just exactly what you're describing.... on practice squads around the league.
Its obvious to me the two main questions for the Cowboys are:
1) Can he be a "difference maker", and
2) Can he stay on the field....
and I'm not so sure they even care about question 2.
Greg Ellis took to coaching, was a good practice player and was disciplined. 21 years ago the Cowboys drafted him instead of Randy Moss.
