Reader mailbag: Worst roster move by Toronto FC?

TFC Republic will feature a regular reader mailbag column where I answer questions from subscribers about Toronto FC and Canadian soccer in general.

I'll respond to the best queries submitted to me by TFC Republic readers, so feel free to drop me an email at jmo1897@gmail.com. You can also reach out to me via Twitter and Facebook.

Here we go...

There was a lot of roster movement by TFC during the season. Which move do you think helped the club the most? Which move hurt the club the most? 

– David Gee    

David asks an interesting question as TFC made more than a dozen roster moves during the regular season, not including short-term loans involving TFC 2 players. 

If we included what happened during the off-season, then I'd go with the acquisition of Adama Diomande as the worst and the signing of free agent Sean Johnson as the best. Diomande has been a complete bust thus far, while Johnson was one of the few TFC players this season who could hold his head up high.
