We can see his true motivation is the cash money. If he was really motivated by another ring, why wouldn't he join a team in the best position to win? The Sox wanted him to start in late June / early July to be fresh for Sept & a playoff run. But they offered $10M less than the Yanks at a prorated $18M. Now he's rushing to the lineup because they need him now. That could have devasting effects on him pitching late in the season.As good as Clemens numbers have been in the NL, he fights a tougher battle against the more potent AL lineups. The other big factor is that he didn't even average 6 innings per start last season. That number is not going to get better in the AL on a soon to be 45 year old frame. So, the Yanks bullpen issues don't improve much having to carry 3+ innings in each start. They're already overworked.
He's going to win his fair share of games - even the Big Unit managed 17 wins with an Era over 5 last season - somehow. He provides a stabilizing force in the rotation, and makes them a better team starting in June. But the Yanks still need to tread water until then and stay healthy once he's hit his stride. Easier said than done.

While the addition of the Boston Traitor doesn't put the Yanks over the top, it certainly heats up the rivalry - not to mention any start Clemens has at Fenway. It's going to be very ugly. He could have had a story book ending to his career here in Boston, but he's now just another NY hired gun taking the money and running. It's too bad because the city would have embraced him as their own once again and all would have been forgiven. As hated and dispicable as Barry Bonds is, Clemens will probably get bigger boos at Fenway this year. Don't bring your kids to those games folks. Yikes...
He does add more theatre to a season where the Yanks looked to be fading away. Now that electric atmosphere returns. Let's hope it dicatates into a Sox-Yanks Sept battle for the playoffs. It's just not the same otherwise...
