My 2 cents:
Poche is interesting - Once his ATH / SPD improve a bit, he'll be a pretty well-rounded SF. His potential in PER should make him a good three-pt shooter, and his potential in BH / FT should make him a very good slasher / finisher.
Randle - it all depends on how high his LP goes. If it improves dramatically, you've got a good starter. If it doesn't get past 35 or so, he's a classic "first big man off the bench" - lots of reb and defense, but not much offense except on offensive rebs.
Crocker - I've never taken a big man with an ATH that low, and when you combine it with no DEF, he's going to be a matador on the defensive end. Plus, you're probably going to have to give him a lot of study hall mins to keep him eligible. Honestly, unless he shows some promise in his first year, I would consider rescinding him.
Franklin - depends on how high his SPD can go. If it gets to 70+, that's a nice SG. If it maxes out lower, he's a decent rotation guy.
Sechrist - I agree with jet. I can live with his low PER, but the BH / PASS are almost unusable for a guard. If his LP improves quickly, try him for a few mins a game at SF and see how he works out.
Ferrell - love him. He's got everything to be a star except the STA. Put a ton of mins into his conditioning right away - if / when his stamina gets above 65, he's going to be fantastic for you.
