Among Poole, Brooks and Livers, I'd say we have three guys who could (no guarantee, but could) be good enough to earn real playing time right away.
Yet at the point, Simmons seems very likely to start, but all reports are that X is having a great offseason.
And then there's Watson - rumored to be working super hard this offseason, and set a team record with a 44 inch vertical, so we know he's pretty athletic.
Some of these guys, through their play, could easily force us to expand the rotation.
And of course, maybe not.
