Welcome Daveyboy.
Brett Wallace may struggle initially if he gets a chance with the Jays, but could flirt with 20 HR potential. In his prime he's projected to be a perennial basher, 30 HR, 100 RBI, but the main concern I have along with many people is his ability to stick at 3B. If he does, then the trade helps the Jays, as they have a more pressing need at 3B. If he is better then Edwin Encarnacion defensively, this allows the Jays to explore a trade with him. If he can't stick at 3B, then the trade becomes moot in my opinion, as they already have a defensive liability in LF in Adam Lind. This would mean either Lind would have to shift back to LF (assuming a trade of Overbay occurs), or Lind and Wallace become a 1B/DH tandem. Then the question is who mans LF? I'm assuming Travis Snider will be put back to his original position (LF).
Michael Taylor has 5 tool potential. He can bash HR's, Steal bases, hit for average, and has a pretty good arm, which could be used in RF (for the Jays). He's been compared to Curtis Granderson, and Hunter Pence, and just appears to be a little more polished then Wallace right now. Jays could use a bit of speed as well, but sounds like this trade will go through.
I'm not bashing Wallace in any way, and think he will eventually end up a 30/100 guy, but as a fan of the Toronto Blue Jays, I'd rather have Michael Taylor right now manning RF.
Kyle Drabek has #2 starter potential, with a chance of being an ace. He needs another year in the minors to develop his changeup but appears to be the real deal. He has a fastball that averages in the mid 90's, that can reach 97 (miles per hour, not kilometers for us Canadians). His fastball looks to have some movement. Along with his + Fastball, he has a 12-6 curveball that was rated the best in his draft class. He also throws a rarely used slider, but the limited video I saw didn't look like a terrible pitch.
Big question mark with Drabek is his mental makeup. (Hence my projection as a #2 starter, but most say he's a future ace) Scouts have questioned it, but also read that this might no longer be an issue.
Overall the price for the prospects was steep. On top of having to trade the best pitcher in baseball (not talking fantasy wise), the Jays had to fork over $6 million to get the pitcher they wanted. (This is all based on assumption).
To the casual fan, this trade might look like a terrible trade - the Toronto Star is bashing it, but I don't agree. I think this was a pretty good return, and much better then the proposed Angels offer.
Both Brett Wallace and Michael Taylor's future are bright. From a fantasy perspective just beware that Wallace may eventually end up as a 1B, or even heaven forbid, a full-time DH.
A little birdie told me that a prospects article will probably be written on the players involved in the trade.
