I don't think I've seen this conversation start yet, so I'll throw it out there....
I think NAU is losing their top 3 this year (Baxter, Day, Lomong) and keeping their others (Beamish, Ferro, Grijalva, and Raff). Given the amount of seniors in the top 25 this year, I think Beamish, Ferro, and Grijalva are pretty good bets to finish in the top 20 next year, assuming all stay healthy. Add to that Brodey Hasty, who must be starting to reap the benefits of all that altitude as a probable top 20 finisher - and I can see 4 already in the top 20 next year. So, as long as their 5th guy isn't way back, I think they have a decent shot of a 4 peat.
To date - the NAU recruiting class looks good, with a couple of studs from Wisconsin (Bosely and Easton). They might need to call on one of these guys for a 4-peat?
BYU will remain strong or stronger given their never-ending line-up. So they will be tough, and might even be pre-season favorites. Stanford and Wisconsin will be relatively weak due to graduations. I'm not sure of Portland Pilots - not sure who all they are losing and how good their incoming recuits look.
Can the 2019 Lumberjacks 4-peat?
