I looked into Bryant at the trading deadline as I've always admired him as a player - perhaps jealousy when the Cubs had him at 3B and we had blackholes...
But with the current direction of the team, I wouldn't touch him. We have waves of rookies coming now... our $$ resources really need to be focused on Burnes/Woody/Adames.
We have Black sitting at AAA and will probably be called up next year (some risk he might not play 3B, but he is there now). Wilkins could also move up quickly. Monasterio has a nice floor at 3B. And what Andruw produced this year is a bit better than what Bryant did in CO. (AM: 242 ABs; 273/349/372; 97 OPS+; 1.6 bWAR vs KB: 251 ABs; 255/342/390; 90 OPS+; -0.4 bWAR). And clearly KB has a higher upside, but that comes with significant injury risk as he only played 109 games in the last 2 years.
While we might still have a weak spot at 3B, Bryant doesn't bring us much upside for the salary and trade capitol it would require. If he was a FA, I might entertain a slightly higher contract similar to Brian Anderson - a base contract with performance bonuses. I don't know that I'd go more than $10M base for 1 or 2 years. 5 years would be a no-go. Maybe Yelli's back issues have me gun-shy about adding another older player long term, but I'd prefer to go with the youth movement at this time and spend our resources trying to keep our current players.
