I think you and I may have discussed this matter at another time. And i partially agree that sometimes TT can be too conservative though I feel the last couple of weeks something has changed: either the coaching staff told him to forget about turnovers and start slinging it more, or maybe the gameplan has chanded now that sammy, woods, clay are all healthy (relatively speaking), or TT turned a bit of a corner by himself. I dont know.
That being said, TT has a combined 23 TD which is top 15 in the NFL in scoring. And he has a league low for INT (i think). So of course hes no drew brees with respect to pure scoring, but being paid what hes going to be paid, he's worth every penny at that rate.
