You could be right and he may miss games, I'm no expert. It's just I am thinking the opposite.
If Mitchell's broken leg is healed, then it is healed and the only concern is his fitness (and touch). It was a clean break and I haven't read anywhere that he had any set backs. The break happened over 12 months ago, so that seems plenty of time for a complete heal. He was looked after by experts with the aim that he will be ready to play round 1 (and onwards), and he appears to be on target.
I don't see him re-breaking his leg (besides a freak accident that could happen to any player), so I don't see a risk there.
He may be rested more in the early games, but then I see him being one of the top Midfielders in 2020.

Outlook (from a broken leg)
If treated promptly and properly, a broken leg usually will regain normal function.
- Because the major bones of the leg support our weight, at least 6-8 weeks is usually required before the bone is healed.

Tom Mitchell gets
through his first serious AFL hitout in more than 500 days unscathed.…...….sitting out the final term on the bench.
"I was a little bit rusty with my hands and things like that, but the body's fine and pulled up really well," Mitchell said post-match.
"I hit a few bodies and pulled up fine from a few big collisions and got through the game unscathed, that's the main thing."
