Jordan had an underachieving, not a horrible, rookie season. As has been written in this thread, he was limited due to injury, the play of our veteran DE's, and coaching. When he was on the field the offense knew it. In his limited time on the field he created havoc a number of times.
Now, this thread is the definition of "HORRIBLE". There are a lot of accusations and fairy tale beliefs (like "it")... "IT" is nothing more than having the ability to play in the NFL. This "it" that some speak of is nothing more than talent and determination. No player has "magic"...."clutch"..."it"...etc....these things don't really exist in the way that some wish to believe.
Jordan is a physical specimen who may or may not last a long time in the NFL. Again, however, he showed a lot of promise during the time he spent on the field.
They found a way to measure "heart" at the combine?
Intangibles. Look it up.
