No...I think it has something to do with the roster optimization that occurs between Year 1 and Year 2. It's the same reason why importing rosters into a franchise can be wonky.
And btw, it's not a HUGE difference, it's more of a 'it feels less 'floaty' kind of thing versus a "it dramatically changes gameplay" kind of thing.
I haven't done any sims yet to year 2 to see how that holds this year or not...but it hasn't changed since CFM was introduced, doubt it will this year.
