Corey Pronman of ESPN had him ranked 6th overall, his scouting report sounds exactly what we need.
The cousin of the No. 33 overall pick in 2015, Mitchell Stephens (Tampa Bay Lightning), Tippett is a very exciting winger to watch. He was a dominant goal scorer this season, due to both the quality and quantity of shots on goal. Tippett is one of the best speedsters in the draft class. His ability to go from 0 to 60 -- metaphorically speaking, though he's darn quick -- is very impressive, and he can gain the offensive blue line with ease. He has a high skill level and can make some open-ice plays, but he's much more comfortable going north-south than east-west. He can kill penalties due to his speed and IQ, and can be a shorthanded scoring threat while doing so. Tippett's game is more about playing in straight lines, but don't let his very tilted goal-to-assist ratio fool you, as he can make plays to his teammates too, a facet of his game that improved as the season went on.
Ranking explanation: In Tippett and Eeli Tolvanen, we have two of the best shot generators and goal scorers in the class. Despite similar types of output, they get it done in different ways. Tippett is an elite skater, and miles better than Tolvanen. However, Tolvanen is a much smarter player. While both are great goal scorers, I do like Tolvanen's shot a little more. Given how close they are, I am persuaded by Tippett getting his production done in the OHL as opposed to the slightly inferior USHL. Then again, it's not easy to forget that Tippett was riding the pine in the IIHF under-18 championship a year ago while Tolvanen was dominating, although Tippett was about as good at the under-17 championship a few months earlier. The skating gap is notable, and I'm not convinced Tolvanen's other advantages close it. Combined with the statistical argument, Tippett gets the edge.
