I don’t think handcuffing at this time of year is necessary, but I get why you want to do it.
I think you have to wait out Michel’s talent; they spent a first on him so he’s gonna get his chances. But he was fumbling in OTA’s and he has spent most of camp in the tub. BB’s the last guy to care about draft pedigree once the pads are on. So it may take a while for Michel to produce. But be patient. November production is fantasy gold. Week 1 - 4 production is nice, but not nearly as important.
As for Ty, I had him in my main league and dropped him for Bilal Powell as the fifth back on my roster. Of course, someone snatched him right up. I know that with Williams and Jones injured and suspended, the GB backfield is somewhat open for a guy like Montgomery, and his pass-catching role makes him secure regardless of who emerges as the ball carrier. You may get an early week explosion out of him while Jones is out and Williams is slightly hobbled, but provided he stays healthy— which is NOT a given; he tweaked his ankle last weekend —I expect him to settle into a low volume, occasional TD scenario. I could be wrong, of course, but that’s what I see.
