Tremble killed an early drive on a third down pass that was off but still catchable. Then, later, he let another pass squirt through his hands and it was intercepted. Yes, the ball was high, but he's got to grab it. Baby Gronk would have corralled both of those passes. Finally, Tremble got called for offensive pass interference.
Junk the seniority system and use the meritocracy system. Baby Gronk is ready for prime time. He's ready to start. Adios, Tremble!
