"
Tailback Karma"** just keeps $hiting in the face of  vile, obese pig 
Fatt Matt for the way he's treated
 Zach Zenner. On a day when his second rate tailbacks finally put up decent numbers (picked up big gains on  some gimmick plays), it appears he's lost his "
rising superstar", 
Keryon Johnson to a knee injury, which could be significant:

Article above notes the Lions actually fared a bit better  running in 2018, after Johnson was injured. Good part of that was Zach, who averaged 4.8 YPC  last season coming off a back injury and was on pace to go way over 100 yards at Green Bay, except Fatt Matt kept pulling him in favor of washed up  turtle LaGarrett Blount, who was too slow to play in Arena League last season.
Not sure how much of  a future Zach Zenner has in New Orleans. It's good they allow fullback Zach Line and Taysom  Hill to run from time-to-time, but once Kamara returns they'll have more than enough "
runners" and he could be  inactive some weeks or  might even be  released again? Would make little to no sense for N.O. to keep both  ZZ and former Motor City Kitten (George?) Washington on the roster once Alvin returns?
I realize this might sound crazy, but if Johnson is out for the year and the Lions are looking to "
trade for a back", 
why not make a deal for ZZ? They can likely pick him up for a "
conditional 7th round pick". And the "
conditions" can be set so high, that there would be very little chance N.O. would ever even get the 7th rounder from Detroit. Something like ZZ has to average 75 or 100 yards per game for the pick to be exchanged?
P.S.: The article mentions the Lions trading with the Bengals for a tailback. Yesterday, both the Bengals "
highly rated" backs had a stunning day: 14 carries for 2 yards, running behind a all Summo line? Not sure who sucks more, the line or the runners?
