Tom Thibodeau is notorious for giving players he loves massive minutes, and that was certainly the case for Grimes last year. The rookie played just 29.9 minutes a night during the regular season but played 42 and 48 minutes in two of this team's final three playoff games. Seeing a sophomore play a full 48 minutes is absurd, but it's less surprising when you see his 37-minute average over the final three weeks of the regular season. That would usually have us ecstatic about his fantasy value in his third year, but the signing of Donte DiVincenzo is discouraging. These two play the same position, and it seems unlikely Grimes plays more than 30 minutes unless there are some injuries in this rotation. It's not like the fantasy profile is glowing either, averaging 11.3 points, 3.2 rebounds, 2.1 assists, 0.7 steals and 2.2 threes on 46.8 percent from the field and 38.6 percent from three-point range. He's one of the better shooters in the NBA, but his role is going in the wrong direction. He wasn't even a significant part of this offense before, with Jalen Brunson, Julius Randle, Josh Hart and R.J. Barrett asked to do so much. All of that should have Grimes going undrafted in most fantasy formats.
