Offensively speaking (forget your precious stats etc) it's about a 'saw-off'. Both will hit around about the same average, one is a more a power guy, while the other is your standard lead of hitter/SB guy. Again both can be valuable to a line up. What Toronto mainly gets in this one is a far better glove at SS. Reyes an 'okay' fielding SS..where as Tulo is one of the best fielding SS in the MLB. This where his main value is when you compare him to Reyes... A better defense helps ANY pitching staff. Less pitches thrown, less times giving the other team 4 outs in an inning or giving them an extra 90 feet, more times taking away possible hits.....etc etc etc
I don't need stats to tell me this, it is simple common sense. Having a better fielding SS (a very key defensive position) helps your pitchers.
All that said however...whether you win by 10-9 or 7-3 or 2-1...it's a W and that's is all that matters. It's true you score 1 run, the other guys have to 1 and another to beat you. I like the other saying too evil twin.
