Historically, it's a nice discussion to speak of our best shooters of the past 50 years (reasonably within the recall of many posters here.
I liked Glen Williams as a medium range shooter. Schaeffer had a terrific senior campaign after Mel Davis went down, and I think his shooting % was around 64% for that season. I don't recall him having 3 point range (there was no 3 pt shot), and in 5 professional seasons shot 47% from the field but only attempted 26 3 pointers out of 700+ FGA, where he shot in the mid 20s, supporting that he may not have been a great distance shooter, more mid range.
Back then I think Looie used point guards to occasionally shoot over a zone or man to keep defenses from packing it in. Guys like Alagia, Kelly, and even Tommy Calabrese could occasionally nail long jumpers, but typically limited to 3-4 tries per game.
McGarry is absolutely right about SJU's strategy, which was basically textbook basketball. Many old school coaches today say that the 3 pt shot ruined basketball. The goal was always to get the easiest shot possible as close to the hoop as possible. The "home-run" shot changed that dramatically.
I like the perimeter shooter we have now, but before anointing them the best ever at SJU would like to see how they perform over a season against the talented teams in the BE. Everything gets bigger and fast when you play better teams, and teams with more talent cover the perimeter better, giving shooters less time and more pressure to shoot.
