Look at Toews. In his draft year the guy had an unbelievable performance in NCAA and the allusion to Sanderson here made was during Toews draft year:

Yet Toews went back to NCAA another year(albeit it was his D+1) but the point still stands he was ready for NHL and went back anyway. What happened after that? Elite right off the bat.
Look at Hanifin, not that far off performance from Sanderson this year in his draft year, could be considered somewhat similar calibre prospects during their draft and Hanifin made the jump to the NHL when he should have went back one more year at least. Now Hanifin is still a legit top 4 but his offense hasnt translated as expected and he isn't the calibre player as expected.
We took our time with Chabot and look how that worked out.
The only way Sanderson should be a Senator next year is if he is forcing the Sens hand and it is his choice fully. Otherwise, there should be NO reason we should want that. I have never seen a defender stagnate due to taking an extra season of development but I have seen them coming a tad too early. Plus, next year we still look to be a disaster, let him take his time and join the Sens with more talent and stability.
The only twisted argument I can see from Sens side is if he comes over earlier, and his offense takes a little longer to develop but that allows us to cash in on a much cheaper deal making him worth much more than what his contract is. Stupid to even think and not worth potential top 5-10 D asset.
I'd much rather see Sanderson go back. Play 25 minutes a night in UND, play ALL situations, work on his puck control and dominate his peers, captain USA and compete for another Gold and best D honors, then step in to Ottawa in April ready for top 4 duty right off the bat a la Makar with all the confidence in the world.
