If Pogacar doesnt want post Tour burnout feelings again he had better limit his spring classics schudule to monuments only (and skip Dauphine). Even then Vuelta would probably be too much ( due to neccessity of peaking for cobbled monuments, which is somewhat different and more challenging due to MVP). IMO its cobbles vs Vuelta choice given that the Tour is a must. Vuelta loses as long as he wants Roubaix
Dauphine or another is part of the prep before Tour, so he wont skip that.
His spring should probably be to do some early race and then focus on the classics.
Just like last season, basically. Starting with TDU doesnt really matter. Spending 2 week in Australia doesnt sound too bad imo. He still go home and have month or so SB. It like can early training camp with racing involved to TDU. Plus it is cool for him and the race for him to take part, if that is really the plan.
And it makes sense to try and win MSR/Roubaix while he still have the best chance to do so. Winning all monuments is something he really wants to do, few has done it so understandable to me.
The choice is kind of easy on what to sacrifice.
