Preseason isn’t months long.THey had months to gel during preseason and practice, in different roles ban they have now. I can’t imagine the envisioned Tatum/Brown or be other kids and pieces playing such a big piece. Bringing him back right before the playoffs, I’d be worried if they tried to integrate him when things are clicking and there was a small chance he makes much difference in the long run for a ring.
I absolutely could be overthinking it and not giving Stevens enough credit, but it’s also not like adding a bullpen piece in August. The system relies on familiarity to an extent. I wouldn’t expect him to be a net negative, I just don’t think he’d be a big enough addition to take them over the top and then in that case, let him get healthy.
