From a Welsh perspective.

Munster v Dragon - Dragons to keep in the game until half time with a couple of nice tries. In the 2nd half after making their thousandth tackle after 45 minutes and bringing on the sub par replacements  they ship a loads of points and lose by 30+

Scarlets v Treviso - I get a erection from the rugby played by  the Scarlets, they score 4 tries but ship a few as well to win by 10

Edinburgh v Ospreys - Ospreys continue to show that their performance n the Champions Cup was  outliers, they struggle to score tries and end up losing by at least 7.  

Cardiff v Zebre - Blues start to gain a bit of confidence and win this by 10, not sure on the bonus point though.
