The OHL i've watched every team play at least once, and teams more local to me (steelheads, colts, icedogs, rangers, storm) i've watched live a couple times in addition to seeing several games each.
Crouse i have that low because i have not seen that offensive upside yet. If or when i do, i'll be happy to place him higher, but for me right now all i've seen is basically a glorified Tom Wilson. Spencer was a tough one because i really do think he can be a real solid all-around mid pairing guy in the same vein as matt finn/jared spurgeon/justin braun, and he's one of the safest bets in the 1st round to reach his potential, but i don't see gamebreaking talent there to justify him in the top 20 especially as a dman. Real good, solid player, don't see him as an impact player. Of course anything can change but as of right now that's how i see it.
