Unfortunately, you din't handcuff Lynch; you handcuffed his handcuff.
Handcuffing is highly overrated anyway, in all but a few cases. Foster/Tate leaps to mind, and Spiller/Jackson may be another one. But you don't really think you can plug in either Turbin or Michael if Lynch goes down and get the same kind of production, do you? Besides that, handcuffs are useless in bye weeks. You're better off with a quality RB3 that you can use in case of injuries OR bye weeks.
