2017 - He was suspended 6 games so he ran for 983 yards in 10 games
2020 - This was the Cabo Mexico holdout year - It was obvious to anyone that he showed up out of shape. He was not football ready and that was his fault. No excuses
2021 - I think he was ready to roll. However, our OLine was terrible at run blocking between the tackles which is his strength. Biadasz and C Will/McGovern were terrible in the middle. Pollard was not as affected by the lack of inside blocking because he is an outside the tackles type of RB. Also, it was obvious Zeke was not healthy with that knee brace he was wearing toward the end of the season
2022 - I think the Zeke/Pollard combination can do big things for us this year "IF" the OLine can correct the run blocking issues. I think this will be Zeke's last year as a Cowboy due to his contract. The only chance he has of hanging around is if he takes a drastic pay cut and that may not even be enough to stick with Dallas.
My philosophy on RBs:
Don't draft a RB in the 1st round ever
Always have 2 good ones on the roster - you don't necessarily need a great one
Keep them through the first 4 years of their rookie contract. When the 2nd contract comes up and they are wanting big money then just let them go.
Draft them with the intention of only keeping them 4 years and replacing them after that.
There could be a very rare exception where you look at the 2nd contract but it would have to be a very, very special RB that had a history of staying healthy.
