Another way to look at it - if Marrone picks Shark and he doesn't translate to the NFL, it would look bad for him because he had so much experience with him. So maybe he thinks being short is a risk or something else is a risk at the next level that he doesn't want to take. Because if he endorses Shark and it doesn't work, it's a little egg on his face. So going in another direction with who the scouts like may just be politically easier.
The SS pick by Buffalo is interesting.
