I'll take him back in a heartbeat. It's gotta be a bit unusual to go to a different team in a completely different role and find your place. It could take a little time. BUT to your point as well. Taylor Raddysh in his elevated role (same thing to consider with Hagel's decreased responsibilities good or bad) has 5 points in 6 games.

somes guys adapt quicker than others, Hagel hasnt been bad at all. hes been up and down the lineup and isnt on the PP at all. im sure if you kept him with guys like Point, Kuch, and Stamkos, and put him on the PP he would have more points

Often takes time to get adjusted to a new team he will bounce back

He's also been line bounced quite a bit.
Colton/Paul/Hagel is looking good though.

Also, Coleman had 1 assist in 9 games before the league shut down in 2020. Been here before.

That's what a new team and a new role will do. He went from 17:28 in ATOI in CHI to 12:09 in Tampa.

Remember Coleman. Paid a big price, didnt produce till the playoffs, helped them win a cup

and then he had one hell of a playoff!
