While I get what you're saying, Dobson is the most accelerated d-man prospect the Isles have had in quite some time. The Isles have traditionally been very patient and have let all of their highly drafted d-men (I will set the criteria at 1st, 2nd, and 3rd rounders) spend their D+1 and D+2 seasons in their Junior leagues (CHL or NCAA) before turning pro. After turning pro, getting AHL experience first was a prerequisite.
Hamonic spent his D+1 and D+2 in the CHL, spent the first half of his D+3 season in the AHL before staying full time with the Isles. Mayfield played 2 years at Denver U before signing and then multiple years in the AHL before making the Isles. Pelech spent his D+1 and D+2 in the CHL and then multiple years in the AHL. Pulock is a little different because he already had 3 CHL seasons when drafted so he only had one more CHL season in his D+1 year, but then spent multiple years in the AHL before staying full time in the NHL. Even Reinbust spent his D+1 and D+2 in the CHL and then multiple AHL seasons. The Isles have always been patient so Dobson (and Wilde as he started his D+2 season in the AHL as a 19 year old) could actually be classified as being "rushed" and not really developed patiently. "Challenged" is probably the most accurate term so far in the Lou and Trotz era.
Dobson is the outlier here and that's a testament to his talent as well as a testament to Trotz' ability to develop him. Some may consider last year as a waste (especially the idiots on the main board and even "experts" such as Proman and Wheeler), but it sure looks like it worked in continuing Dobson's development to have him looking this good at the NHL level in his D+3 season and a week after his 21st birthday. Recall that most pundits considered Dobson needing more development time than the "more NHL ready" d-man prospect such as Bouchard since he already had 3 CHL seasons when drafted and an earlier 1999 birth year. Bouchard hasn't established himself in the NHL yet. Thanks again Edmonton for gifting us Dobson.
The main point here is that Trotz and Lou are infinitely better at their jobs than the previous regime, but they have done the opposite of being patient and fast tracked Dobson and Wilde. Wilde's unfortunate high ankle sprain last year along with COVID screwed his season. Even Bolduc is ahead of the typical schedule, he is going to be in the AHL in his D+2 season.
You are completely right that people are making smart decisions, but it has been the accelerated development path becoming the norm now.
