I wouldn't go as far as to call the current situation a logjam, but Kremer deserves a mention as being better than the mediocre/below average tier. Certainly more than Suarez. He's not an All Star but guys like him don't grow on trees, either. So that's, when everyone is healthy, four average-or-better starters, plus Means who if nothing else should be very good for a 5.
Having Tyler Wells as a setup option should transform the entire pen. His career slash allowed as a reliever is .168/.212/.319.
