We can agree to disagree, but I stroooongly disagree. He's a tight end - one of the easier positions to fill. One bad apple can certainly spoil the whole bunch. Weighing risk/reward (chances of him being Gronk vs. average; chances of locker room disruption vs. drop off in talent with next tight end up) - I would pass.
Outside of Baylor and it's one data point of case study which was riddled with so much failure that it's nearly impossible to replicate when has one bad apple spoiled the bunch?
