Bell and Fournette should've been obtained the moment they were available. I mentioned this in the past as they became available. Bell, Fournette, Johnson & Johnson as the 3rd down back options. David would've remained strictly by default.
I also liked the idea of putting a player package together in order to obtain RB, AJ Dillon from Green Bay before the deadline. I think Green Bay is proving to vulnerable at this time and Watt might've been a good move to help on defense.
Boy .... Could we ever use a big work horse like Dillon ! I was pleading for him during the draft, and he is being under-utilized now. JJ is having a good year. I felt that he would love to be with his brothers .... and the Steelers are definitely Super Bowl contenders this year .... but then again, Green Bay is right in his hometown backyard. Opportunities galore for JJ .... and a player of his caliber should not end his career without a trip to the BIG GAME !
