I think youve done really well for yourself! You could cap either of t hese guys still, so no missing a season doesnt hurt too bad. It would be tough to get thrm to u21s from here, although Berger could go close. Id work out a plan long term for both and go with it. For me, id train Berger to be an amazing PF, get the inside skills really high, because hid secondaries are already fairly good for now. This will turn Jensen into a SF. After a few seasons get some one on one, OD and JS fwds into them. I think its important to give some JS becasuse Berger has good range for a big, so beerfing up his low JS will give him some ok 3pt %s.
Good luck, let me know if you want any help along ther way!
