I'd take Brind'Amour and Blake, depending on how small the league is.
If it's a 4 team league, you might risk dropping a really good player to make room for a player you're getting. If it's a 12 or 20 team league, go for it. Brind'Amour should hit at least 70 points, and Blake's probably good for around 60, which is more than enough to make up for what Savard produces (probably close to 90).
If you're telekinetic and you know it, clap my hands!
Savard in a keeper league, for sure. Brind'Amour is aging and Blake is as well while coming off of a contract year in which he put up career highs. Savard is a better point producer than either of the two and will be around considerably longer. If you're close to winning now, the Brind'Amour-Blake side is better though, as they will produce more points than Savard alone for the next few seasons.
