Teixeira is not an above average player Dojji. Try to defend all you want, but Tex is an elite level player and you know it. Your rose colored glasses make it hard to see that sometimes. He would have been a substantial improvement over Lowell in both health, defense and offense.
Now in terms of going forward, I think a move was going to be needed even if he proclaimed himself chipper and healthy as his production has taken a nosedive. His OPS per month is as follows:
April .912 OPS
May .816OPS
June .607OPS
Not only that, but he isnt walking and his OPS is driven mostly by his power, which was incredibly inflated after the first month and wasnt sustainable based upon his prior career norms. Add to that the fact that he is a statue at 3rd and you have a guy who is detracting from your ballclub. Thing is, if Papi hadnt gotten hot, the fanbase would be all over Lowell right now. But winning takes away that sense of urgency for now. That being said, a lineup with 2 of the trio of Green, Lugo, and Lowrie in it for the long haul would be fricking great from where I am sitting.
