I'd just caution that I did get 4 pops in 6 weeks but he likely had a high sub-level so you might get 4 but I can guarantee that you'll at least get 3. If you want him to have a nice start you could always train OD for 10 weeks to get him up to Prolific-Sensational. IMO I wouldn't worry about JS/JR just yet if you're in a low division (like I am) because a high OD will shut down the other team's scorers if you're in a low division and will make you competitive very quickly. Others will probably disagree but if you single train him over the next two years in OD and Passing then you'll have an excellent defensive players who can pass and then you can round out his other skills over the following 3 years. That's what I'm doing with my 5'9 guy. Also, your player's salary won't increase substantially for a couple of years regardless of what you train.
I wish there were pigmen. You get a few of these pigmen walking around I'm looking a whole lot better. Then if somebody wants to fix me up at least they could say, Hey he's no pig-man!
