I'm confused... is that one deal or three?
I'm assuming it's three separate deals, but wanted to clarify.
Who else is on your roster? I agree with the drafting plan in theory, but there are some players that are better to have regardless of any other factor. MCab is probably one of those players, IMO, but it's hard to say for sure without seeing the rest of your roster.
You should also look at the other teams and their likely keepers - are you sure you will be able to get adequate value if you take the extra draft picks? If you are the only one in your league using this draft strategy, you could find yourself missing out on top level talent.
