I would move Hansen for Smoltz, definitely. I'll pass on Livan, though, an ERA pushing 6 in the NL isn't all that attractive.
I'd give Weaver a shot before Livan.
That was against AAAA teams. Honestly, other than the Mets, none of the teams they beat were really impressive. Isn't Tampa one of the inferior teams in the AL?
I'm not overreacting, I think the Red Sox are easily one of the top 4 teams in the AL. The fact remains, with Wells and Clement on the DL, they only have a 4 man rotation right now, maybe 3.5 with the way Lester has struggled to give them innings. I think Snyder has the ability to help the team out by keeping them competitive in games. I agree with you that there is no need for a full blown panic move, but it's clear that Jason Johnson isn't the answer.
