If it is true, does that one year age difference really make a big deal?
How many "pops" can one reasonably expect to get over the course of a season assuming (a) one-position and (b) two-position training?
I've never used Demo but the 2 best players of last year's draft in my league were 1-2 ball prospects for me. I scouted them and was able to get one.
If I you get a stud draftee and in a low division it's probably better to sell for long term since the draftee's going to blow up on you. then in the future when you do have the cash you can spend that cash on a stud draftee.
