Quick pros and cons...
Tigers---Great starting pitching with the best pitcher in baseball. Power hitting lineup. Good Manager
Giants--Excellent Bullpen, outstanding defense, timely hitting, great attitude. Good Manager
Tigers---inconsistant bullpen, weak team defense, lack of lefthanded pitching
Giants--beat up starting pitching, lack of power. Posey and Pence in major slumps
To win, Tigers need starters to pitch well and go deep into the games, and their hitters need pound on Giants starters
For Giants to win...get to the Tigers bullpen, win games late by not getting behind early, and take advantage of their opportunities
One last thing for the casual fan to look for....these games will all be played in what are universally called the two best ballparks in MLB. Setting aside Wrigley Field and Fenway Park which are historical , AT&T and Comerica Park are just outstanding venues. Ballplayers and fans alike love these two places, and it's kind of neat that they will be featured in the WS.
