GB either:
didn't like what they saw in practice, so they cut loss before losing pick;
or
GB liked what they saw in practice, and after Davis clears waivers they can sign him as a FA and not give up the pick to KC.
Makes PERFECT sense!
Tennessee did this to us a few years back on a FB [Quinn Johnson??] we traded for a cond. pick
SF also this week promoted Dujan Harris to 53, maybe because GB came'a sniffin. SF gave him 13 touches, perhaps to showcase for a cond. pick. At any rate, SF has 4 HBs on roster and when Hyde is healthy they'll probably cut Dujan again and if interested, GB can get him for free.
Monty with sickle cell trait can be an unexpected scratch for any game going forward. The good news is as it gets cooler the odds of SCT acting up goes down.
