How Brady has used Kincaid as a blocker is kind of interesting. Brady has been getting him downfield to block guys on the second level in different formations and personnel groupings (extra lineman in particular), and honestly Kincaid has been doing a pretty good job at this - many times absolutely demolishing a secondary player pursuing Shakir, Cook (angry runs win), etc. It’s definitely part of the play design, but he’s certainly shown the “want to” needed to help others get extra yardage. I swear almost every time there’s a big run or YAC play Kincaid is near the ball carrier at some point blocking. It’s been fun watching him and these big WRs terrorize secondaries with their blocking, especially during this winning streak.
I also think people forget that it usually takes TEs a long time to come into their own because of all the extra skill sets they need to hone. That’s part of why top TE prospects aren’t a bad choice in the first round; extra year on rookie contract, weapon/safety net for your QB, big pass catcher that can block LBers and secondary players.
