It's been said that Marinelli was the primary catalyst of Taco being drafted from the start, although the FO surely went along with it. It seemed a shame that Taco could find a way to co-exist with the guy who helped him get his start with the Cowboys. Rod Marinelli is reputed to be a fairly demanding coach. Unfortunately, some players aren't willing to submit positively to that approach.
Additionally, Taco evidently harbored an attitude of entitlement and was hyper-sensitive to criticism, whether it was constructive or not. His negative reactions to the fans on twitter seemed to reveal an over-sensitivity to criticism. I'm hoping Taco is able to overcome the difficulties in Miami that he had with the Cowboys. If not, his future may be foreboding in its nature.
