Ah fair enough, ty for all the details. Although, that would still be quite the outlier. 1.75” (or 1.5”) in 7 months may be ordinary at say 14, but it’s extremely unusual at 18. On average men grow ~0.3” in 2 years from 18 to 20, with certainly plenty of variance, but anything over 1” after turning 18 is quite rare, especially in just 7 months.
But certainly, if it’s over 7 months, and he’s rounding up, then yeah, 1.5” over 7 months does seem more plausible than 1.75” over 4. Still extremely rare at that age, though. It’s possible, but I’d still side towards there being some exaggeration, along the lines of a “generous” measurement where he’s lifting up his heels and they aren’t really pushing his hair all the way down, so that he’s maybe 5’9.25”, not 5’9.75”. If you’re a small NHL prospect, especially a dman, size is soooo important to your career, it’s human nature to lie a bit, which makes me doubt unusually high growth that isn’t backed up by rigorous, unbiased measurements (like at the combine). But who knows, he could also be a real extreme outlier in terms of grow rate at 18.
