Guess I don't keep up with scouting reports but I have heard very few people say Strome was going to be an 80 pt two way player. His play style always reminded me of another Islanders pick in Tim Connolly but with a willingness to shoot more and a much more gritty demeanor... also without the terrible personality that followed Connolly since he was 17.
I've often said Strome was TC 2.0 minus the totally botched handling of TC's development by Milbury. Injuries contributed later on, but he was completely rushed and MM toyed with his head and confidence. It was a real shame. You're right that TC and Strome have similar skill sets, but I think Strome has better hockey IQ than Connolly.
Strome's situation has been the polar opposite with being allowed to develop properly and having a good support structure in place. Training with Tavares and other Isles in the Dungeon (even before being drafted) obviously helps in that regard. Strome is coming into a really good situation on LI as he won't have to come in and be the man. He knows he has a chance to be the Robin to JT's Batman as he'd be another offensive catalyst for a team that really needs one. With all the talk of Strome moving to wing, his development path looks very similar to Logan Couture's. Allowed to develop in Junior, start out in the AHL (all signs point to Strome starting in Bridgeport), breaks in as a winger alongside a premium center in JT (Big Joe/Tavares), eventually moved back to center.
The Isles may have learned their lesson after rushing Bailey and Nino.
