For me, number 5 is clearly the best. A starting pitcher with 90 vR, good control, and decent pitches? And throw in high stamina? I'll take him. That said, there are a few questions. I'd want to know what his current ratings are in order to see whether he can actually reach the projections. Don't post them here- otherwise other players in your league might see them and get a free scouting report - but take a look at where he is now, then go back to the draft history in your league and see how much progression other 22 year old high-drafted pitchers have made. You'll probably find that vR and vL can increase by about 15 points each for a 22 year old, but pitch 1 usually won't go up more than 10 or so. And durability and stamina won't go up much at all, so where he's at now is about where he'll end up.
The other player I like is the second baseman, but I definitely want to know more about his defense. Can he stay at second? If so, he's an elite player. Rank him second if he can. After that I'd put the other starter. If he had slightly better splits, he'd be an ace.
