A trend is a steady overall pattern of increase or decrease. He missed 5, then dropped down to 4, then dropped down to 0, then jumped up to 10. There's no steady pattern of increase or decrease in that.
If his last four years has a pattern to it, then he should miss 5 or less games next year and then less games than that in 2 years and no games in 3 years. I see that as manageable and not that unusual in today's NFL.
