Why not roll Dak out there? Oline is beat up and you are just gonna sit Dak in the pocket? Cmon linehan, look what's going on out on the field. ridiculous play calling.
Martin walking better to the locker room than he did off the field - but that knee has taken a lot of hits in last 3 months (brace on already for mcl damage, and hyperextended in preseason), and that roll up was how most ACL tears can happen. Hope it is not major - best player on offense this year.
