Keeper help, WHIR

[hstlives]

Its a 10 team head to head keeper league in year 5 with a ton of categories:
R, 1B, 2B, 3B, HR, RBI, SB, K, AVG, OPS, IP, W, L, CG, SHO, SV, K, ERA, WHIP, K/9
And positions are
C, 1B, 2B, SS, 3B, IF, OF, OF, OF, Utl, SP, SP, SP, RP, P Bn, Bn, Bn, Bn, Bn, Bn
We keep 5 players each year. My four definite keepers are:
Arod
Utley
Votto
Halladay

And I'm torn for the 5th keeper. I can keep Cano, Morales, or Markakis. I've been waiting 3 years for Markakis to turn all those doubles into HRs and last year he actually regressed, so I think I'm done with Markakis. So unless there is plenty of sediment out there in favor of Markakis, the question becomes: Is Morales' power for real and sustainable, or should I go with the .300 15 80 80 line I know I'll get from Cano?

Markakis did drop off a bit last season but still drove in 100 runs. He's only 24, you give up on him this season and you can almost be sure he'll finally put up those numbers you've been waiting for. I'd still keep Markakis, if you feel too strongly against that then Cano would be my 2nd choice.

If possible i'd try to trade those guys in a 2 for 1. If not, then i'd go Markakis.

No real chance for a 2 for 1. With only 10 teams and only 5 keepers, most teams have at least 4 very good keepers. I am trying to shop these guys around to make my decision easier, but no takers.
