I hate to be this way, but I've gotta say it. It isn't good enough, and it wasn't good enough, for Jack to be average at assimilating and developing talent. The Mariners had hit (we THOUGHT!) rock bottom in the last year of Bavasi. Everyone said the cupboard was bare. Jack needed to be, indeed he WAS BROUGHT IN to be MUCH better than average at finding and developing ENOUGH talent to restore the fortunes of the team. Average just wasn't going to cut it. They were too far down.
Brass decided to go all in with the draft, and the draft was going to have to yield such a good core of young players that it would lift the team enough to add in veteran talent, which combined with the young core, would yield a consistent contendeer. THAT was the vision. How do you lift a club with NOTHING into SOMETHING with a what Jack found, traded for, and developed? You don't. You need PLUS PLUS performance to do that. (I hope people know by now that my caps are not for SHOUTING, rather they are for logical emphasis.)
IMO Jack was not even average, but if I am wrong and he was average or even slightly better, that is FAR LESS than he was required to be given his mission. Unless, of course, the M's were going to be content with what it turns out they've been.
