Dex was a fun guy to play with in S20. He comms well, his DM is solid as is his gamesense. If he continues putting in the time, he will definitely be a good bubble (even playoffs) scout for S21. He still needs to continue working on his positioning as medic, but could def play at a bubble level on that class, too. Bear in mind that his ping will be terrible on any server that isn't Colorado. And sometimes Colorado as well.
Bottom line is that he's a nice kid who deserves a good team. I don't think he's the kind of fragger who carries teams per say, but he will be that guy who always performs well, gets the frags he should, and improves the mumble atmosphere too. Pick him up!
