Maybe, if he was your only prospect. But if everything goes well, we are entering a period where we have a LOT of guys who are valuable prospects. If you squander a year in a season where he will only play 2 months, then the very first year he is on the 40 but not the 25, someone has to be knocked off. Repeat that for 4 or 5 guys and you are releasing a lot of talent.
To me, nothing would be better than to have him called up in 3 years and add him to the 40 as you add him to the 25.
