I love Mack Hollins. Wish we had kept him, and think it was a mistake not to re-sign him for what NE offered. That being said, the talent level is higher this year-- the execution isn't. Largely that falls on coaching imo, but drop-offs in effort and/or comfort among players will do that, too.
God, do I miss Mack though. Amazing locker room guy, and a fantastic example of making a career out of doing the dirty work.
