I'm not liking the team all that much. Look like a power outage on offense. Holliday and Gonzo will be the only ones to top 30+ homers IMO. I only see 170-180 homers out of that team. 1 or 2 more big bats would come a long way.
The rotation is also a bit iffy. I like Lackey and Young, but Liriano is a huge risk. He could pay off big time however. Buchholz and Bailey are too unproven for my tastes.
You have good closers on paper, but Hoffman is old and finished poor last season. Ryan also missed most of last year. High upsides but more risk.
I'd probably drop Bourn and Escobar for Percy and Sherill. You already have a ton of speed (Roberts, Furcal, Crawford, Ellsbury, etc.) so you can dump Bourn, and while I like Escobar he has less upside then Loney and Hamilton.
I honestly think you should pick up Percival for BJ RYan. Ryan has come off Tommy John surgery last May and it usually takes at least a year for a pitcher to fully recover from it. Plus, a healthy Jeremy Accardo is most likely going to be taking his place in the relief lineup, so Ryan may not see consistent action until late May, or June.
I like how you're going with youth with Liriano and Buchholz. It may be a gamble, but there are huge payoffs potentially with those two. I am never one to argue with drafting young prospects. I mean, lok at my team, over half of them are either rookies or sophomores. Overall, your team is solid, with only a few hitches in the pitching staff.
I for one would NOT drop Ryan for Sherril or Percival. Neither one of those guys is guarateed to close for any amount of time, but Ryan (who it seems is ahead of schedule) will be the closer all season if healthy. I might be more tempted to drop Bourn and pick up one of those closers in addition to who you have since Hoffman scares me this season (and there are NO closers available in my 12 team league!). Another option, since Bourn has value, is to try and trade either him or Ellsbury (you don't need both) for someone with a little more pop (or another closer). You'll likely end up playing Hamilton ahead of either of those guys anyway. Starting pitching is a little scary. But it could be very good depending on Liriano and Buchholz. I for one like them both this season. Don't like Bailey though. Not in THAt park, with THAT manager. I'd keep him on a short leash and watch the waiver wire. The team needs some work, but has potential for sure.
Put in James Loney! The dude will be batting at least a .300 avg with 100+! That'll be a whole lot better than Gonzalez. Even though Gonzalez may have a better ability to smash home runs, Loney won't be far behind him that stat category either. James Loney is elite when it comes to 1B this season.
I would watch out for BJ, his time will be seriously limited, but I always say you can't have too many closers. Same with Hoffman. Clay and Homer are excellent but untested and you can always play matchups if either don't workout. Sherrill is a fantastic lefty but won't be very valuable in your format. I like your offense a ton, I like that you have an excellent bench incase someone doesn't pan out, and if everyone does... tradebait.
