It is somewhat inconclusive to answer such a question, as there are a lot of unforeseeable dependent variables in deciphering a team’s ability to generate a profit over a course of a season (i.e. “timing” of the wins and losses, whether they are unable to cover their heavier favorite money line wins). Also, the markets anticipation and strength of the Dodgers seems right in line with yours, as their current over/under win total is 88.5, making it hard to generate alpha returns in excess of the vig of 162 games based on your 85-90 win forecast. All in all, rarely is such an approach prudent, and the teams that are able to generate a return over the course of a season (i.e the A’s last year grind out in excess of 20 units) one should still make the case of being able to pick your spots on such alpha teams can generate a higher ROI.
As far as the Dodgers go, expect them to come at a premium in more games than they will come in as undervalued, as they carry some big name and commonly overpriced starters that give them less margin for error with one of their prolonged hitting slumps that they experienced twice last year that resulted in a small profitable season. Teams that possess such volatility are much more attractive stand alone bet teams.
