I'm not going to jump onto the 'he has a heart problem, don't take him' bandwagon. It completely depends on what exactly the heart problem is. All heart problems are serious when you're an athlete and should receive immediate attention, but some are less serious than others. Its completely possible that overall effect of this problem may not affect his playing ability or durability. We should wait to find out exactly what this means before blindly assuming he'll never be safe to play again.
I'm just thinking about this kids story. And how he came to Utah and how he was regarded as the #1 pick . To dropping significantly, most likely. He will lose millions.
