We could sure use a .256 OF'er whom plays plus D.
The time is almost up on some of the prospects' years of team control, and it doesn't look like anyone of DD;s traded is going to make a big surprise.
As it turned out, DD kept Devers and a few others look to be better than the vast majority of prospects he traded. It worked out for DD, because one, we won a ring and had 3 first place finishes, and two, the prospects he chose to trade away have not lived up to the hype. Thirdly, he drafted pretty well for having crappy picks and a restricted IFA spending pool.
That being said, we can't assume every farm is going to peter out like much of that one did. We also can't assume we choose the right ones to trade, next time.
I still think the best idea is to keep most of your best prospects in hopes a few can add some very low cost value to the 26 man roster, and maybe a trade, here and there, when needed badly. Many times, it has worked keeping our homegrown stars and solid role players.
