Actually I think I find the 80m and 90m teams harder to build, myself. I had a specific plan in store for 60m and found two guys who fit perfectly, everything kind of fell into place after that.
At 80m and 90m however, I know what it takes to win OLs but they aren't typically filled with 20+ HOF owners. I feel like there is going to be a lot of overlapping strategy and general team construction so I've been trying to figure out something to give my teams an edge. I'd hate to end up with a team nearly identical to several other owners and then end up with the worst record of them just because I was the one who got stuck with a random bad performance or two (I'm looking at you, Babe. Thanks for nothing at 140m buddy).
