The crazy thing to me watching him is that he doesn't appear small. I get that his height/weight are lower than the standard for his position, but I don't see it on the field. This guy is a star. Fast, slippery and powerful. Up and coming and still proving himself, but he literally jumps off the screen at you. I would have a hard time trading this guy unless I got an absolute haul in return. Certainly not looking for a buy low sell high type thing for another RB. There are only a couple RBs out there I would trade him SU for at this point and his value hasn't reached those absurd levels....yet.
I'd trade him now if I could get back a star QB. I drafted Burrows and beginning to think he isn't going to improve this year.
All depends on your RB depth and the league size/setup I suppose, but I would have a hard time trading him for any QB outside of Mahomes, Hurts, Allen, Tua or Lamar, and at this point I don't think his perceived long term outlook gives you any chance at a trade like that. I believe he will continue to rock, but so far he's only done it in two weeks and while he has looked great it will be difficult to sustain RB1 production on limited touches per week. Burrow plus Achane to someone that likes to buy low? Possibly, but football is a fickle and Burrow will get right, we just don't know if it will be next week or week 14. I know nothing about your league setup, but after the elite 5, guys like Purdy, Love, Dobbs, Mayfield, Wilson and Stroud are playing as startable fantasy quarterbacks. If one of these guys is available I would personally be looking to bench Burrow and either play matchups or pick up one of the current top 14'ish options until he gets right.
All that said, the previous poster suggested Richardson + for Achane. That would be an interesting one. Richardson's fantasy needle is also pointing straight up and he could end up a top 5 option at the position when the season wraps.
