We could see a lot of pops initially in different skills per player. But I really think it will be the rarest of players who cross-train pops in the same skill more than once. The thing that I like about it and find interesting is that if you have a rotating training regimen you could very easily see speeds a bit faster, as a skill could get a primary, secondary, and tertiary pop in consecutive weeks. I like this change because I actually prefer multi-skilled players and lower salaries. And if in eight seasons my cross-trained team can play multiple positions with low salaries, it will perhaps allow me to splurge on the high salary superstud.
Once I scored a basket that still makes me laugh.
