He's got good speed, and a compact body that will allow him to play physical (though not to move people, but hold his own in the corners and along the boards).
Friedman lacks any "special" quality that would allow him to get by on talent while he learns the game, which is why he'll need at least 2 AHL seasons and maybe 3, but he has enough raw talent that he could be an effective D-man once he understands how to play the game.
Most defensemen aren't uber talents, they're guys with good instincts and enough talent that they develop into reliable players after a few AHL seasons.
Gudas had 3 AHL seasons.
Vegas is a good example:
Engelland: 2 1/2 ECHL, 4 1/2 AHL seasons, didn't start until he was 28 (a bit extreme!)
McNabb: 3 AHL seasons, started at 23
Merrill: 3 college, 1/2 AHL, started at 21
Miller: 2 AHL seasons, started at 23
Sbisa: #19 pick, started at 18
Schmidt: 3 yr college, 2 years between AHL/NHL, started at 24
Theordore: #26, 2 years between AHL/NHL, started at 22
Washington:
Carlson: #27, 1 year AHL, started at 20
Djoos: 3 yr SHL, 2 yr AHL, started at 23
Jerabek: Czech league, started at 26
Kempny: Czech league, 1 yr KHL, started at 26
Niskanen: #28, 2 yr college, started at 21
Orlov: 2 yr KHL, started at 20, between AHL/NHL, then back starting at 22
Orpik: 3 yr, college, 2 yr AHL, started at 23
SSS, but it gives you a flavor of player development, a few break in early but a lot of defenseman don't become starters until 22-24 and then need a couple years to get comfortable.
So even if Morin only plays spot duty as #7 towards the end of the year, at 24 in 2019-20, he won't be exceptionally old.
Friedman only turns 23 in December, 3 yr college, 2 yr AHL is not unusual.
